Step up from your stock cooling fan and heatsink to the MassCool 5T321B1H3G. Designed for use with value-driven Intel processors including Core 2 Extreme, Core 2 Quad, Core 2 Duo, Pentium D as well as Celeron D. The copper base and aluminum heatsink and 3 Heatpipe provide the cooling performance you need to keep your desktop running at its peak.
A long-life, ball bearing 92mm fan quickly draws heat away from the cooler's fins at a lively 2,800rpm. A flexible 4-pin PWM connection delivers automatic fan-speed adjustment, so you can enjoy the efficient cooling and minimized fan noise.
Pros: I have a friend who had a damaged stock heat sink. So, last week we took a look around on newegg to see if there was a good heat sink he could use to replace the damaged one. We found this one. After seeing what it did to his machine I ordered one.
Cons: Its a bit loud at full speed. But, thats easily fixed by running the fan a bit slower, its not going to do too much to performance.
You do have to remove your motherboard to install it, however, if you want to your cpu to run cool its worth the slight hassle.
Other Thoughts: I did a bit of comparison using SSE3DSoak (SoakMP.bat) on a Pentium D 820 (@2.8ghz).
MassCool Heat Sink is 38% cooler at idle, and 55% cooler at full load then the stock Intel heat sink.
On top of all of that, I have MassCool heat sink set to run at 50% fan speed (which is almost inaudible). The Intel heat sink would speed up 2500rpm from is low speed at full load, the MassCool speeds up to a grand total of, well 0...During the test the machine did not get hot enough to increase the MassCool's fan.

Followup Review: IMPORTANT!!!
Reviewed By: Seth on 8/31/2008
Tech Level: somewhat high - Ownership: more than 1 year
Pros: This is a followup to a review I had posted last year (look for it below.) I still think this is or rather has the potential to be the best price to performance ratio LGA775 cooler on the market. But, there's BIG caveat, depending on the number of silicon layers/thickness of your motherboard!!! Read the cons!
Cons: After about a year of using this on a Gigabyte GA-P35-DQ6, I decided to do some case upgrades which necessitated removing the motherboard from the case. Part of the process involved adding temp sensors to the 8WA741 heatsink. As I did so, I noticed something alarming. The heasink, though fully tightened, was not fully pressed/seated against the CPU! Though the gap was slight, the heatsink wasn't even tight enough to squeeze out the excess heatsink compound! No wonder I never could get my Q6600 to temps comparable to others! Well, long story short, the problem is that the heatsink's attachment bracket that fits to the backside of the motherboard has threaded inserts that are too tall and stick through and well above the front side of the motherboard. So, when tightened down, the heatsink's clamps lose about 1mm of clamping distance, and that's not good for anyone's CPU!
Other Thoughts: Oddly enough, even without being fully seated, the 8WA741 still cooled my Q6600 relatively well. [I never had any overheating issues and very few crashes (not directly attributable to heat issues, though can't be sure), even during intense gaming.] And, after a little modification, it's perfect. I had some thick gasket material (non-conductive) and cut out a piece using the retaining bracket as a template and attached it between the bracket and the motherboard. Now, the heatsink clamps are able to fully tighten down again the motherboard surface, and there's no longer any gap and all the excess compound was squeezed out. Now, my CPU temps average 5 to 10 degrees C cooler, depending on the CPU load. So, ultimately, I still recommend this cooler, but only if you take the precaution of adding a shim of about 1mm thickness to the retaining bracket! So, don't let this design flaw in only the bracket convince you to unnecessarily spend a bunch more on an overated, brand-name heatsink!

Did you?
Cons: Didn't cool very well, looked like it didn't fully set on cpu. OEM fan cooled much better that this one which i went back to.
Other Thoughts: it is sitting on my work bench collecting dust. A waste of 30 bucks.

Fan Failure
Reviewed By: ben f on 1/26/2010
Tech Level: somewhat high - Ownership: more than 1 year
This user purchased this item from Newegg
Pros: Kept CPU very cool in comparison to motherboard/VGA
Cons: Failed shortly after 1-year warranty
Other Thoughts: The "long-life" ball bearing fan is failing me after just 15 months of daily usage. Average RPM is below 400. System is now unstable under heavy load as temps approach 59C. Great while it lasted.

Keeps the i5 in good temp range
Reviewed By: Chismo on 1/25/2010
Tech Level: somewhat high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: - Socket 775, so it works with the AsRock P55 Extreme board - Three months of keeping the i5 750 in good temp ranges (no overclocking as of yet) - Secure, but slightly tricky, back plate mount
Cons: - Nadda
Other Thoughts: - Used on an AsRock P55 Extreme board with Intel i5 750 - Didn't try out the i5 stock cooler, but temps run from around 35C idle to ~60C after 30 minute Prime95 stress test with MassCool cooler (no overclock) - Didn't use enough grease and had poor contact (not mounted tight enough) after the first install attempt. Idle temps weren't bad, but shot up to 80C in the first few seconds of stress test. Yikes! After re-greasing and re-mounting, temps were pretty good.

Highlights
Superior Heat Dissipation and Cooling Performance The copper base and 3 copper heatpipes conduct heat fast; high-density aluminum fins maximize heat dissipation area, plus a 92mm, 2800RPM cooling fan to deliver optimal cooling performance.
PWM Function The PWM function automatically adjusts fan speeds according to the CPU temperature for efficient cooling and minimized fan noise.
