Pros: THIS REVIEW HAS BEEN UPDATED AFTER DEEPCOOL'S RESPONSE TO MY FIRST REVIEW. SEE NEW NOTES IN OTHER THOUGHTS.
+ Outperforms MANY water cooling solutions
+ Largely thoughtful design considerations for motherboards. The fins are clipped so you don't run into issues with your motherboard plugs.
+ Truly does offer semi-passive cooling if you want it. You'll need at least one case fan for exhaust and to promote airflow within the case, but I have a totally silent one that works more than well enough. Without the case fan things eventually get toasty by the end of the day of normal use, it's still doable but I hardly think it's worth it when you just need one silent case fan to give you insurance. See my various temps in the Other Thoughts row.
+ At passive or low fan speeds this is a deadly silent cooler.
+ Fan has a nice rubber housing to reduce vibrations.
+ Thoughtful mounting hardware and very sturdy backplates. My motherboard barely flexed when installed and I could actually install this outside the case. Other HUGE heatsinks will flex the motherboard too much due to stupid hardware. This was a very pleasant surprise and a huge plus. Considering how many configurations it supports I don't think you can get any better than this.
+ This is easily the best bang for buck heatsink I've ever come across* (When the included fan works*)
+ Overkill HUGE packaging. Which is actually important for delicate fin configurations. It's thoughtfully designed and it's cardboard so it's easy on everything. I don't see this heatsink getting damaged in transit.
+ Thermal compound is more than suitable. We're talking about only 3 degress "hotter", at most, than Arctic Silver.
Cons: - Fan can only reliably face one way on the heatsink. Due to the fan's design and the mounting solution they provide, it will eventually clip the heatsink.
- My fan was defective. Silent at the lowest speed but it made a very unique drone at medium or higher and I know this fan shouldn't make that type of noise. It's hard to describe but it's unlike any noise I've ever heard a fan make, even at high speeds.
- You'll need at least a 6" long screwdriver to finish screwing the heatsink to your motherboard. This might pose a problem for some.
- While the heatsink itself clears the RAM modules the fan may not. You can technically mount it while resting on the RAM, however this might be an issue if the heatsink barely fits your case like it did my mid tower ATX NZXT Source 210. The heatsink itself barely fit this case, actually rubbing on the panel when I close it, but if the fan is slightly higher than the heatsink then I couldn't close my case. You can reverse mount the fan on the other side if you want to but the fan itself will eventually start to clip the heatsink when it settles in.
- This is what kills the product and brought a 5 egg down to a 2 egg: NO CUSTOMER SUPPORT! I e-mailed them twice (once before for something else and once for this review) They totally ignored both e-mails with the first being over a month ago and the latest a week ago. There's also no support number I could find to call them and they only offer "support" through e-mail, which again was totally ignored and totally unacceptable. Therefore the "warranties" they provide are useless. It's a real shame because this is an amazing product. Considering that the fan is almost 20 bucks this is no small problem whatsoever. It's basically a third of the cost you paid for.
- Not really a con given my incredible passive temps but the nickle plating does have a ripple effect and the finish had knicks and scratches in it. I was tempted to lap it down to get a truly flat surface but I decided to leave it as I got it and it didn't seem to matter.
Other Thoughts: REVIEW UPDATE:
Deepcool condescendingly, borderline insulting, reply to my review gave me no further results from their supposed tech support and "proper" e-mail. Here's my problem with their attitude, THEIR website's support e-mail is different from what their reply on newegg was for the first two months, and after I checked yet again before this update was it finally correct by month three. Yet, it's no wonder it's "my" fault according to them despite emailing them at the "proper" address they provided in their response. So, terrible support gets even worse. 3 months with 2 emails every month at every e-mail supposedly related to them resulted in 0! responses. Not even automatic and yes all my e-mails were professional and cordial, even praising. I never changed it from my first inquiry.
Everything about this cooler still stands, and frankly, I'd still take a chance on a bad fan simply because this cooler is still awesome and top of the line, especially for the price. I also don't see many other reviewers talking about the fan so it should be safer now. Just know that Deepcool is a terrible company when it comes to support and you should expect absolutely zero support from them. If deepcool ever gives me proper support I'll be more than happy to bump this up to a full five eggs.
END OF UPDATE
My temps on an i5-4570 not overclocked in a 21C room with Prime95 for 1 hour load tests:
Stock Intel Heatsink: 35C idle 90C full load with fan at max
Deepcool Lucifer V2 passive (1 case fan): 29C idle. 65C full load
Deepcool Lucifer V2 fan on low: 27C idle. 54C full load.
Now where it truly shines AMD 6800K APU. This is a hot running chip that only has a thermal barrier of 75C
Stock AMD heatsink, not overclocked: 40C idle. 72C load
Deepcool Lucifer V2 passive: 32C idle: 55C load
Deepcool Lucifer V2 fan on low: 29C idle. 44C load
I was able to get my highest overclock yet on this chip with the Lucifer bringing it up to 5.4 Ghz, a full Ghz more than stock and a 65% increased GPU overclock:
Deepcool Lucifer V2 passive: Didn't dare try.
Deepcool Lucifer V2 low fan: 40C idle 60C load.
Truly incredible for a low thermal barrier chip that definitely runs warm. Overall, this cooler EASILY BEATS Corsair's and CoolerMaster's lower end water cooling solutions. If your case can fit it, get it.
This really is a fantastic cooler but when a primary component arrives defective and you cannot get any customer support whatsoever, I cannot give it a good rating. If Deepcool gets their act together and actually acknowledges their customer's existence I will definitely update this review. If you don't mind taking the risk of getting a bunk fan, definitely go for it. This is a great cooler with an incredible value just be prepared to substitute the fan if necessary.
This review is from: WD Purple WD20PURX 2TB SATA 6.0Gb/s 3.5" Hard Drive
Pros: + A proper drive for real surveillance needs. What this means is that this drive was designed to handle reading and writing multiple streams at once (Up to 32 camera feeds reliably, for instance). This is actually rather difficult for a normal-use hard drive to reliably achieve without stuttering, drops or other random performance issues.
+ In a practical test of 12 cameras at a heavy load of 1080p at 30 frames per second running for one day this drive kept all the video up to speed with no drops and no stuttering. I used a standard desktop oriented 7200 RPM drive to compare and I'd get random drops and stutters here and there. It's not the hardware of the Purple line drives more than it's the firmware. So when you see, "it's only a RED or GREEN drive lolol" it's only half the truth.
+ Appropriately powered at an average of 5.2 Watt peaks, 3-4 average.
+ Quiet, cool and low vibration. Key requirements for a long living 24/7 drive.
+ 2TB is almost just enough to handle a week of storage for 6 cameras at 720p and 24 fps.
Cons: - Compared to the competition of other surveillance drives this drive performs a good bit less in write intensive situations. This drive strives to balance read/write performance equally more than one over the other. As such 32 cameras is definitely the practical limit for this drive. Though depending on the configuration I wouldn't even go that high, maybe only 16 cameras at 1080p, 32 at 720p and a lower frame rate.
- Doesn't have proper sensors to ensure reliable RAID/NAS surveillance storage. While you can technically do it, I wouldn't. Seagate's consumer solutions, for now, offer better scalability and performance in that respect. Say about 15% better performance and up to 16 drives in RAID arrays where WD only suggests up to 8 with Purple.
- An average 3 year warranty for this type product. Not good, not bad, just standard. However, my experience with WD customer service has been a mixed bag to this day. Their support staff would rather deflect responsibility on their part than actually investigate why a product of theirs failed, and that's if they even address your actual problem at all. To them, it's inconceivable it was due to a defect on their end in any way. However, if you do have a standard failure within the warranty period RMAs are of average quality, always re-certified junk (that bothers me if the product fails within the first month. I bought NEW not refurbished, WD) But in all honesty that's just the sad standard that this industry implements at the moment. Things won't be much different with Seagate, though they do offer better customer support instead of just playing the blame game. Of course, as always with customer support YMMV.
- This isn't a con but since I don't have a time turner I cannot vouch for the reliability of this drive over the long term. If and when it fails I'll definitely update my review. As it stands, I don't see any reason for it to prematurely fail under normal conditions and I've had this drive running 24/7 since I've received it with no signs of quality degradation.
- Another "not a con" but definitely needs to be addressed is that I don't see any documentation about this drive supporting outdoor climates. While WD claims these drives handle heat differentials I don't think they mean outdoor winter to outdoor summer temperatures. Which is notable as I know quite a few people implement surveillance systems in non-climate controlled structures. Since WD has yet to get back to me on that question, I cannot say for sure. Perhaps they can respond to this review with actual outdoor (but properly sheltered) operating temperatures, if any.
Other Thoughts: I intentionally avoided using benchmark numbers with this review because I feel they're a misrepresentation of what this drive intends to do and how it operates in the real world under its intended application. While you technically can get a better drive, benchmark-wise, it won't always perform as well due to firmware features the Purple line implements. This drive is designed around the idea of caching streams so you don't incur drops and it does that well.
The WD Purple basically performs like a NAS drive until its firmware kicks in with features to help balance surveillance workloads. This is not a good drive for storage NAS, access and write times will be less optimal and sensors that help balance RAID loads are absent here. This is definitely not a good drive for desktops or OS drives as everything will be less than optimal in that performance arena.
Depending on what type of performance you want this may not be the drive for you. Seagate's surveillance drives, for instance, off better specific scenario performances, particularly in writing and RAID setups. WD chose to go with a more balanced approach in which it doesn't win many real benchmark battles but it does achieve a respectable balance between everything.
This is definitely a good starter drive if you don't know where to start and don't have a crazy high end and demanding surveillance system, and if you do know what you're doing but have a smaller system this drive shouldn't disappoint you, either.
This review is from: GELID Solutions GC-VGA02-01 1 Ball, 1 Sleeve VGA Cooler
Pros: + Absolutely spectacular performance over reference stock blower heatsink designs. I dropped 30 degrees at load and 20 at idle with fans at lowest speed. From 80 degrees at load to 50 and from 50 at idle to 30 idle on a GTX 680.
+ This even beats most 3rd party heatsinks by a decent measure, like Gigabyte's three fan configurations.
+ High board compatibility.
+ A LOT of peripheral heat sinks to satisfy most cards and situations.
+ The fans are UV reactive and look like bioluminescent blue jellyfish if you have a UV light. It actually looks pretty cool but then, how many times are you going to stick your head at the required angle to notice?
Cons: - Tedious installation but honestly, what do you expect?
- The thermal tape provided for the smaller heatsinks can be a little lackluster, but if installed correctly pose no problem. Here are some tips: Use 80% or higher isopropyl alcohol to clean the ram and vrm surfaces thoroughly, this is important as it evaporates faster and cleans better. Do one at a time, don't clean them all ahead of time. Put the heatsink tape on the heatsink FIRST and leave the last paper film on it while you gently but firmly rub the heatsink on a flat hard surface like a table or desk. Then apply it firmly to the ram or vrm chip. Don't fuss with it. Get it right the first time. Also be sure to plan where you're going to run the fan wires first, as they will knock the heatsinks off if you're not careful. If you're installing this on a GTX680 a heatpipe will hit one of the vram heatsinks, use the lowest profile heatsink included to avoid this issue.
If you do that they won't fall off. I did two lazily and they did indeed fall off just from gravity. Do it right and it's no problem. You just need patience. I prefer it this way since it works and you can remove them without damaging anything. It's a practical win-win.
- This is perhaps the most idiotic and dumb design decision on this heatsink and it's that the fans aren't PWM. They're missing the fourth wire so while you can plug it into your card you CAN'T control them through your card and they will run at a very noisy 100%. I absolutely HATE this. It's ALMOST a deal breaker for me, but if you have a spare fan plug on your motherboard you can control the speed that way. At low the fans are quiet, nearly silent. It's just infuriating that you have to do it this way and it can't dynamically be controlled by the card itself. But, at the huge performance gain you get with the heatsink, it's not really necessary to worry too much about the fans.
- The heatsink and fan alone takes up two extra slots. So it becomes a three slot card. It's difficult to know whether it's worth it or not as they don't offer a slimmer version, but given the results it's a concession worth having if you have the room to spare.
- Instructions leave quite a bit to be desired. They're not the worst I've seen but they're also not terribly helpful. When in doubt, watch a youtube video of someone installing one of these.
Other Thoughts: Despite a rather wordy Con list and a near dealbreaker fan situation I can't help but love this heatsink cooler. It just works and works extremely well if you install it properly. I also don't think it's difficult to install at all, just a little tedious but how else are you going to maintain a broad compatibility?
Ultimately, this is quieter than most stock fans and cools quite a bit better to boot. If you have a requirement for either, GET THIS. It's also worth remembering that graphics cards these days prefer to throttle performance rather than increase fan speeds so it's definitely worth have a cool card.
