Cooler Master Hyper D92 - CPU Air Cooler with Dual 92mm Offset Push-Pull Fans and Accelerated Cooling System

If you're in the market for a cheap, effective CPU cooler...get a 212 EVOIf you're like me and you have a poorly designed mid-tower case made by the SAME MANUFACTURER (CoolerMaster Spec-02) this cooler makes the best out of a bad situation. Here are the specs on the system I tested the D92 onCase:CoolerMaster Spec-02Fans: 2x 120mm front, 2x 120mm top, 1x 120mm bottom, 1x120mm rearCPU: i7 4970k (tested at base 4.4ghz and OCed to 4.7ghz)Thermal Paste: Arctic Silver 5I originally ran a CoolerMaster TX3 on my i7 4970k(OCed to 4.7ghz), which was decent for most everyday tasks. Temps were avg. 38c at idle which I found to be a little on the high side but nothing that would damage the CPU long-term. When I ran Prime95 I noticed the TX3 struggled severely to keep temps below 95C (which WILL damage the CPU long-term). AIDA64 produced a similar result. GPU Bench Marking utilities, such as Valley and Firestrike saw temperatures on the CPU hover near the high 60's. I re-seated and reapplied thermal pasted 3 times just to be sure there wasnt an error in mounting or an air bubble in the paste but the results were the same, which is to say that the TX3 just could not cope with the high running temperatures of the i7 4790k. Even at base clock temps dropped across the board around 2 degrees.Enter the Hyper D92...Compared to the TX3 you get a similar mounted height, 1 extra heat pipe, and a far FAR superior mounting system. The design of the D92, although larger than the TX3, allows for 4mm more room near the first RAM slot (which was un-usable with the TX3 mounted). the twin 92mm fans included in the D92 are the same as CoolerMaster fans sold retail, where-as the TX3 came with a single generic fan out of the box. Without the use of a sophisticated decibel meter I was amazed at how QUIET the D92 was. At 100% with all other fans off the noise was almost identical to that of the TX3 with its single fan! With the other case fans at 100% I can't hear the D92 at all.Now for the moment of truth.I ran Prime 95, AIDA64 and the GPU benchmarks and came to a startling conclusion. Load temps across the board were down on average 15C. The highest I could reach in Prime 95 at full load (Small FFTs) was 84 degrees, far better than the 100C (temps wont read above this on my rig, but it was PEGGED at 100C during the Small FFTs) on the old TX3. Idle temps were down also, averaging 33C while ambient remained roughly the same.Bottom LineIf you need a low(ish) profile cooler like I did, I haven't seen a 92-mm package that competes with this. That being said, if you can fit an EVO 212 in your case i'd go for that first just based on the fact that its far cheaper and at max RPM will be quieter running. If you have a mid-tower/mini tower, the Hyper D92 is a great choice!

First off, I am new to the whole aftermarket coolers thing, so I was a bit taken aback by the plethora of choices offered by Amazon and many other sites. I wanted something which would keep my heat down, and maybe OC my i7 930 (Just a bit) but many of the heavy duty coolers are so large they block the ram slots. I use Patriot Viper RAM which has large heatsinks, they were not compatible with nearly any of the other products, so I took a step back and found this guy. The d92 is huge, but not nearly as huge as some of the others and was compatible with my ram. Sold.I average temps with my aftermarket cooler was about 60c idle and 75c underload. When I OCed I was at 86c. After installing the CPU my idle temp is average 32-34c under load about 50c. I have yet to overclock due to other issues arising nonrelated to the CPU cooler. That is an impressive increase in heat dissipation for $40.The Good:It is big. Very big, small to medium towers may still have difficulty fitting this thing, I have a large case and had no issues, just be wary of that. I consider its size a good thing due to the large amount of heat sinks and double fans. Size does matter and here it shows and succeeds.As noted above: a 20c decrease in temperature from my stock cooler.Easy to install. I did have to take out my Motherboard from the case to get the back latch on, but I expected to do this. The Process was straightforward and idiot proof. Needed only a screwdriver.No gimmicks. It is a spartan object, not there to look pretty, or do pointless crap or sate many CPU builders dreams of having aesthetics be more important than functionality.Quiet: I personally don't care about audio from fans. I don't notice it and never have, but it is indeed slightly more quiet than my stock cooler and I suppose that is good to know for those who do care.The Bad:There was only one incident with my cooler. My first install caused half my RAM not to be detected. I don't know why or how, but after some some spent trying to figure out what the heck happened, I reinstalled the Fan facing the secondary direction (blowing the heat up and out instead of directly back and out). Now my motherboard detects all ram again. I reversed the fan again to actually see if that was the cause and sure enough, it stopped the memory from being detected. I don't know how or why, but it does.Conclusion:Good. A good working fan, easy to install worth every penny of its price. Just be wary of size in your system and check your RAM capacity after install.
