fanless heatsink keeps cool

white Reviewed By: czbo on 11/8/2008
Rating + 5
Tech Level Tech Level: high - Ownership: 1 month to 1 year
Pros: good looking and efficient cooling. Can attach a big fan if needed. Easy to install.
Cons: very large, check dimension to make sure it will fit.
Other Thoughts: In my small form factor case, this heatsink keeps my Athlon 64 X2 5000+ at 36C at idle and 50C at full load, without a fan. Granted, there is a power supply fan right above it sucking warm air out of the case, so if that is removed, the CPU would go to 60C at idle (not good). Another concern I had before buying was whether my RAM modules would bump into the heat pipes. On my GA-MA78GM-S2H motherboard, the RAM modules fit with a very small clearance. Any RAM module with fancy tall heat spreader on it will not fit.

Pros: This is a great heatsink, it has broad compatibility across platforms and is easy to install. Originally I used mine on a socket 939 setup with an Opteron 144, and later an X2-4400. It did an amazing job cooling the Opteron, I'm talking load temps in the low 40s overclocked to 2.8 GHz and 1.58vcore. It did a fairly good job cooling the overclocked X2, although not as much as I would've liked. I'm currently using it with an E6600 and it does a good job keeping the processor cool with load temps in the low 50s using a 1.55vcore. Mounting to socket 939 or LGA 775 is easy if you do it with the board outside of the case, I have not mounted it to an AM2 board yet.
Cons: It costs almost as much today as it did a year and a half ago when I bought mine. Also, it doesn't include a fan. Those are minor and unrelated to the actual operation of the heatsink, the heatsink itself is excellent.
