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!

Pros: It keeps the CPU cool, as requested :) The horizontal fan is nice for my rig, allowing me to vent the CPU air right out the back.
Cons: You have to take your motherboard off to get it on. Not a problem if it works the first time, but...
I've noticed that the fan is making a slight ticking noise. I believe that the fan is brushing against the casing or something. I'm concerned that this will lead to the fan becoming unbalanced before too long. I'm not sure if this is just my fan or whether this is a common problem.
Other Thoughts: I do like knowing that my fan is secure on the CPU. I purchased this after one of the locks on my stock fan came loose a year after being attached (seriously!?) and my CPU over heated.
You would think that with all of the engineering power at lnte| they could figure out a way to 1) securely mount a fan without a hastle, 2) without worrying about snapping your mobo in half.

Pros: This heatsink is very quiet and keeps my processor very cool. It was easy to install.
Cons: None so far.
Other Thoughts: Just be sure you remember to attach the base bracket under the motherboard before you set on top of the CPU.

Good "Budget" Replacement for Stock H/F
Reviewed By: Stumper55 on 11/3/2009
Tech Level: high - Ownership: 1 week to 1 month
This user purchased this item from Newegg
Pros: Can't seem to beat it for the Money, and it will only get a little better once the Heatsink compound levels out. My E8400 CPU dropped from 130f to 118f ( no load ) and from 155f to 130f loaded.... and they are both slowly creeping down a little bit :-)
Cons: The size,,, for a 92mm fan, it almost makes me think about wishing I had gone for a 120mm, but that would have been more $$$ Having to take the PC Mobo apart... Wish Case Mfg's would catch up and leave a CPU sized blank spot on the back of the Mobo mounting plate.
Other Thoughts: If you hate the lousy Retail Heatsink fan combo's the Mfg's are providing with thier retail packages these days,,, this cooler at least make running your PC tolerable!
