Pros: What I was expecting was a nice cooler to replace my XFX stock cooler in which the fan bearing was going out, and I didn't feel like sending my XFX 5870 back in for the 5th time (2nd time for a cooler-related issue.) Instead, I opted to get an aftermarket HSF cooler. This one ranked high on my list for it's price and user reviews. It promised cooler temperatures and a better cooling solution. Mission Accomplished. Not only does my card run about 3-4C cooler at idle and 7-10C cooler under load than with the stock cooler, but the fans at 100% are nearly silent. There's almost no difference in sound between 30% and 100% fan speed. At first, this concerned me, but after monitoring the temps for a little while, it's a non-issue; the fans work perfectly fine. I also like that the fans are controlled by the card. It's stuff like this that makes me a believer in aftermarket cooling solutions all over again.

Cons: It's a 3-slot cooler, so it takes up the 2 slots that my 5870 takes up, plus an additional slot for the fans. I can't see myself needing that slot anytime soon, so it's really no big deal for me. Just keep that in mind if you have a lot of add-in cards plus a big video card... This cooler does take up additional slots. Also, installation can be a bit tricky. There are 4 black stand-offs you have to use in order to properly mount the cooler. While it is necessary, it would have been better if you could have attached them either to the cooler itself, or instead, used a backplate as a guide. I'm not saying it doesn't work, but it could have been designed better. You'd better have 4 hands and a flashlight if you want to install this cooler correctly the first time.

Overall Review: VGA Cooler works as advertised, and it does so unobtrusively. Job well done Arctic Cooling. I am indeed a fan.

Pros: + great cooling capacity for a Radeon 5850 + near silent - even @ 100% fan speed + fans plug directly into video card (no fussing with power connections)

Cons: - didnt use the included ram/vrm heatsinks but it was nice to get them. I might use them somewhere else (see below) - as others have stated, way too much thermal paste comes pre-applied to base of cooler. I removed it and used an appropriate amount of <my own> for installation. Most manufacturers do this though for people who slap and run so I didn't knock it for that.

Overall Review: Was pleased to find this fan works with the stock baseplate on the 5850. Mine is a Asus model. Utilizing the stock baseplate is rumored to yield better ram/vrm cooling, with no worries about attaching the individual heat sinks included. I did have to slightly "adjust" the heatpipes (pressed them up tight against the cooling fins before installation) on the cooler to accomplish this but in the end it worked out real well. Though I didn't purchase this cooler for additional cooling over stock, it performs better than stock nontheless. If you are looking to replace your 5850's fan that has started wearing out (as many are lately) this is a good choice. Do yourself a favor and web search how to use the stock baseplate with this unit for a tidy, professional looking, and well performing combination.

Pros: I was using a stock cooler on an Asus Radeon 5850 that sounded like a vacuum cleaner was competing with a leaf blower when it was under load. After a bit of light overclocking, I was hitting 81C on average with spikes into high 80’s. I purchased this aftermarket cooling to solve these glaring sound and heat issues. Here’s the results: -Temps went from 80C to 51c under full overclocked load. -ambient sound went from “landing aircraft” level to a video card fan quieter than my quietest case fan. -I did a happy dance.

Cons: They did not include 4 of the screws in the packaging. It took some genuine innovation and the cannibalization of the stock cooling device to attach the heat sink instead of waiting the week or so to get the company to send the necessary 4 tiny screws. It was a really screwy installation without having received the necessary screws. To sum up the cons: -This product would have been waaaaaaay better if they included the missing screws. -The thermal tape sucks. I cleaned it off and used thermal epoxy on the RAM sinks. -Installation time was crazy long due to lack of screws. -Aluminum sinks suck. I purchased copper ones to stick to the card. -The included washers interior diameter was made to fit the missing screws. -Fan is large enough that it blocks an additional PCI port. -MORE SCREWS PLEASE! overall, I gave it -1 egg due to lack of screws, thermal tape, and aluminum heat sinks ... But mostly for the lack of screws as I was aware of the other issues prior to purchase.

Overall Review: Installation would have been MUCH EASIER, if they deigned to include the necessary attachment components! (aka…please include the necessary screws next time) I used a very thin layer of Arctic Sliver 5 instead of the included thermal paste because apparently that makes a huge difference. A friend of mine used the included thermal paste on his first install of this product and he could still hit 66C from time to time. He now has Arctic Silver on it in the hottest case imaginable (a very high ambient temperature) and it maxes at 58C. He claims with astonishment “58C is actually cooler than the ambient temp within the case itself!”

Pros: I replaced the stock heatsink for my Radeon HD 4890, with this bad boy.. First, it fits perfectly on the 4890, with no adjustments need. The install was fairly simple. Right from the install my VGA temp was lowered from 57C at idle to 40-42C, at load I used to hit 80+ sometimes on stock... with this VGA cooler, it doesnt dare go over 65-67C... Highly recommended if you want a cheap/easy/safe way to cool your VGA

Cons: Really none, except the heatsinks stick pads didnt really want to stay on the VGA that well, put with a little effort you can keep them in place. (Use an eraser and wipe over RAM units before placing these on)

Overall Review: I was amazed how much this VGA Cooler lowered the temp.. It fit right on my Radeon HD 4890 perfectly without any mods.

Pros: Cools temps down about 10c idle and a bit more at load. Quiet. memory heatsinks stick well if you properly clean the chips.

Cons: Not so much in crossfire(CF), fans are almost touching the second card (3 card slots). I could not get this to work in CF on 6870s. Each card ran fine seperately but would hang/lockup once the game got underway in CF. Put the original cooler back on the main video card (left the cooler on the 2nd card) and CF works fine without lockups.

Overall Review: Great single card solution, definitely recommended. I believe there just isn't enough room for proper airflow between the two cards in CF.

Pros: - Straightforward installation process - QUIET!! - Keeps the card cool

Cons: - None so far

Overall Review: My PC used to be very loud from fan noise. Whenever I would run anything intensive on my video card, the stock cooler fan from XFX would spin so fast to where it was hard not to notice the noise coming from the computer. The card would idle around 40c and rev up to 65c. Now with this cooler, the card idle's at 33c and piques out at 43c at higher load than with the stock fan. This will consume 2 additional expansion slots in your case. Make sure you have space in your chassis prior to purchasing! PC Specs: Intel i5 750 | XFX Nvidia 9800 GT | 8GB DDR3 | | 1 WD Black 1 TB drive | 1 OCZ Agility2 60 GB SSD | 1 Maxtor 250 GB (for testing) | BluRay drive | Avermedia TV Tuner | 1 Thermaltake 430W PSU

Pros: Easy to put on. Runs fairly quiet at full speed. Basically silent at minimum speed, which I keep it on, and it stays completely cool. For non-intensive usage, you could actually run this completely passively, the heat sink is that good. It actually kept cool enough during testing without the fans even plugged in, that i could run it that way permanently even with the gaming i do.

Cons: Some of the smaller heat sinks on my card didn't clearly match up with the instructions, so it wasn't 100% clear where they should go (many of the small rectangular chips all look alike, and were not in the same position as the reference pic), but in the end it all worked out fine.

Overall Review: The vapor-x cooler on my 5870 was never anywhere near as quiet as this thing is, and the fan started clicking within a year. This was a great replacement and didn't take long to install at all. Very happy with this. I bought it mainly for noise reduction, but it has a phenomenal cooling potential as well.

Pros: I bought one of these for my XFX Radeon 5850, whose fan had died. To put it simply, this is the Chuck Norris of GPU coolers. With a 125 MHz OC (core clock running at 850 MHz) and memory running at the stock 1000 MHz, here are some temperatures: Idle: 33C. Furmark: 63C. Gaming (DiRT 3 @ 1280x1024, every graphics setting maxed out): 45C max. Bitcoin mining @ 1000 MHz core/350 MHz memory (yes, I got a lucky card to run that high at stock voltage): 57-60C. It is also quiet, I cannot hear it over the sound of my other video cards.

Cons: The heat sinks come with pre-attached thermal tape, which some have had trouble with. I have not had any issues yet, but I'll keep an eye on them. Also, a bit large, card now takes up 3 slots, but I suppose you can't have everything. The pre-applied Arctic Silver thermal compound covers an area much larger than is needed; I cleaned it all off and applied my own Arctic Silver 5 compound.

Overall Review: Make sure to clean the surfaces of the VRM and RAM before sticking the heat sinks on, or they will not stick. I just bought 2 more of these for some of my other cards...
