This review is from: ZALMAN CNPS9900ALED 120mm 2 Ball Low-noise Blue LED CPU Cooler
Pros: Purchase this last Zalman 9900 cpu cooler in late 2009 and just had to update my 7/1/2009 review in the interest of info sharing with other pc enthusiasts. Until this month I had a total of 2 of these Zalmans but sold my oldest Zalman 9900 cpu cooler having upgraded to a refurbished Corsair H100i water cooling upgrade. I originally paid over $40 for the Zalman some 4+ years ago and sold it to a work associate who just wanted to mildly overclock his 4770k. Offered to let it go for $35 along the installation and he agreed. This was a "win-win" for all he was guaranteed a 4.2GHz o/c on his 4770k which I would guarantee and I would recoup $35 thereby lowering my out of pocket cost on the Corsair H100i to just $55. For those who are still on the fence about going with a air cooler you should seriously consider the Zalman products simply because the manufacturer supports all the sockets presently out there including the new Haswell-E's. Quality of Zalman coolers are top notch and the longevity of the ball bearing fans speak for themselves...4+ years and still going strong. All that's needed is the bi-annual cleaning with a good industrial air compressor. Just be sure and blow out both the video card fan, power supply fans and any dust bunnies you have accumulating with the mid or full tower case. Again, I avoid using toothbrush or any brush since it potentially introduces static which might occur. BTW, the bottled heat sink compound provided with the original Zalman 9900 cooler is among the best pastes out there. A few drops of rubbing alcohol (isopropol or grain alcohol ...whatever you having laying around) will remedy a infrequently used bottle of this paste). Should Intel come out with another never ending socket platform down the road a quick call to Zalman will get you a bracket kit to accommodate newer sockets down the road .... never ever had issues with Zalman support...top notch!
Cons: Zalman has both a aluminum and older copper finned cooler. I prefer Copper over aluminum .... why fix what isn't broken?. The Zalman 9900 has outgrown it's usefulness for aggressive overclocks but is still better than the stock Intel cooler
Other Thoughts: This cpu cooler plays nicely with Haswells for mild overclocks so if you have one of these legacy coolers think twice before you toss it out. It does help when dis-believers see a 5 year old air cooler happily chugging away overclocking a 1st gen Intel 4770k to the tune of 4.3GHz with no throttling whatsoever...YMMV!READ FULL REVIEW
Pros: This is my very first "platinum" certified power supply and my review below clearly champions compelling reasons why you should consider Corsair in your very next pc build and/or upgrade. From initial unboxing to powering up this beast exudes quality with attention to design and assembly. Externally, the case is rounded on some edges adding a somewhat "come hither" attraction unseen in almost all other power supply cases. This is a "platinum" certified power supply and a very generous 7-year warranty from the manufacturer. Platinum certification means it is at minimum 92% or more energy efficient at half it's designed max power output. Multiple video cards configured for either Crossfire or SLI bridged configurations will NOT overwhelm this bad boy. Corsair provides more than enough cabling and because it is a modular design there is no unsightly unused cabling cluttering up your mid or full tower internals. This is a modular power supply with an overabundance of cables. Corsair again provides the usual imprinted pouch similar to all their other power supplies which allows the user to store all unused cabling.. For those who have purchased other Corsair products such as their CPU water cooling products this HX1000i power supply also has Corsair Link capability allowing the user to monitor power supply vitals such as temperature, power usage, fan speed, etc. There is also a unobtrusive LED indicator light which flickers during periods of Corsair Link activity..
Internally, components used to assemble this power supply use very high quality components such as 105 degree Celsius spec'd Japanese Rubycon branded capacitors but more importantly circuitry to output power without a energized fan being exhausted until power draw eventually makes a call for fan cooling. I suspect the 7-year warranty offered on this power supply is very modest and should provide way more than 7 years of reliable service. Does anyone remember the Samsung TV debacle a few years back when they cheaped out, used inferior 80-degree substandard Taiwanese caps, and had massive quantities of warranty repairs the majority of which involved faulty leaking caps? FYI, quality electrolytic capacitors (ex: Nichicon, Rubycon, Nippon, etc) are imprinted with "105 degree" on the outer casings and almost always have higher quality electrolytic material internal to their canisters. The fan is nearly silent during spin up and you will have to strain to hear if the fan does indeed rotate as it is that darn quiet during use. There is the existence of a handy fan test button on the cabling side of the supply which is used to test fan operation. My research informed me the Hx1000i fan will almost always remain de-energized since fan cooling is only required during moderate to high power draw .... WOW on this one! Fan, btw, is a high end fluid bearing design which is way superior than the anemic bronze sleeve bearing designs and even more durable than ball bearing designs. My
Cons: Corsair Link requires usage of either a SATA power connection or a powered USB header connection so be sure and be cognizant of this fact for planning purposes. Fan test switch should have been on side of the power supply on/off switch ..... were Corsair engineers asleep during this switch design session?...duh! While on the subject of this ill suited location of the fan test switch both the activity indicator LED along with fan test switch should have been placed on the side of the power on/off switch otherwise case covers have to be removed to either test the fan or get a visual of Corsair Link activity via the LED. Older or entry level motherboards might not have spare/multiple motherboard USB headers so be sure and complete your due diligence prior to purchase otherwise you will have to forego using Corsair Link software.
Other Thoughts: Pricing of the Hx1000i might be perceived as extremely high but you obviously get what you pay for. Corsair web site as usual is easily accessible 24x7 and support is top notch. I have a Corsair H100i CPU water cooler and have never had a issue which speaks volumes about Corsair quality. Do not be overly alarmed if the fan on this Corsair Hx1000i power supply hardly ever spins...this power supply is "that" efficient! You can, however, proactively increase the longevity of this high end investment by blowing out your workstation case/power supply/video cardfan a minimum of twice a year with a good air compressor. I normally perform this preventative maintenance task in late Fall (before Winter when it's a PITA to drag out the compressor) and especially before Summer (when pc components are under extreme heat running during the hottest months of the year). Be amazed how much dust/dust bunnies is expelled when you use a good air compressor versus a can of compressed air! I'm not overly enthusiastic ever using a toothbrush like others for cleaning pc parts (it introduces risk of static electricity to delicate components) As usual, Newegg shipping and tracking is stellar ... UPS tracking numbers are issued in a promptly manner by Newegg allowing me to status location and delivery times until actual delivery is made to my doorstep.....kudos again Newegg!READ FULL REVIEW
Pros: Should you scroll down on the reviews for this Rosewill power supply you will see I originally posted my initial review in January 2012. Some 2-1/2 years have elapsed and this power supply is still performing flawlessly (hope I don't jinx it by updating this review) powering my son's Asus P6X58D Premium motherboard. Either I am one real lucky purchaser who just happened to get a cherry picked supply or Rosewill has some decent quality controls put in place. Whatever reason there is, I just had to post this update having just blown out all the dust bunnies from the case when I took note of the date of purchase I scribbled on the supply itself. Fan still turns extremely quietly even with all the dust/dust bunnies hanging off the fan blades and shroud. Cost per year for me now averages to roughly $30 on this particular power supply which is unheard of especially with my past luck.
Cons: I took note of other postings on this product and see it's still the "luck of the draw". Suggestion for others is....blow out your cases a minimum of twice a year (Fall season before winter and Spring time before hot summers is perfect for me) with a good air compressor honing in on the cpu cooler, video card fan, but more importantly the power supply. You will be amazed at the cloud of dust you create even in a well cleaned house.
Other Thoughts: Power draw on processors, power supplies, and video cards are continually going up each year and heat is one of the primary factors why components fail. A good indicator when you need a good cleaning is when you start getting BSOD's on a otherwise stable o/c'd pc workstation where you factually know is optimized and stable. I've seen pc's where dust bunnies have literally clogged up all ventilation openings even to the point where they have prevented fans from turning and yet the workstation still performs. It's doesn't make it right however it goes to show parts manufacturers design properly even when consumers neglect/abuse or worse case fail to perform basic preventative measures thereby shortening the serviceable life on their pc parts.READ FULL REVIEW
