PRODUCT TESTING & PERFORMANCE COMPARISON
Test Bed Setup:
Here is what I will be testing these coolers on:
Xoxide Enlight Breeze Pre-modded Case (Provided by: Xoxide Modifications)
Shuttle AK31 v2.0 (Provided by: Xtreme Tek Werks)
Duron 800 (Pencil Unlocked)
Vcore 1.85 volts
512megs Crucial PC2700 DDR Ram (Provided by: Crucial Technology)
Western Digital 40Gb 7200rpm ATA-100 Hard Drive
ATI Radeon VE
Samsung SW-232 32X CD-RW (Provided by Samsung)
Standard 1.44 meg Floppy
Windows XP Pro
Artic Silver was used for all testing in the test bed
All idle Temperatures were taken after an hour of idle time with only MbProbe running to take the temperature measurements. All Full-load temperature's were taken after a full one hour of running prime95's torture test.
Testbed temperature was a climate controlled 24 degrees Celsius with all included case fans running during tests. For information on the airflow for this case go HERE < -- link is not correct.
Now, I will have to mention one thing about the H2Twin. This cooler is just a little too big in my taste. It's sheer size almost led me to frying my CPU totally. Here is why....
Here you can see that the cooler is very close and every slightly overtop of the northbridge cooler on my ak31. Well, low and behold, the cooler was actually perched on the fan. The cooler was only cooling half of the chip. I found that the temperatures of 50+ degrees Celsius was normal for this board until I installed the TAK and the temperatures dropped to under 40. Well, needless to say, I had to remove the fan off of the northbridge to actually install the H2T properly. So, let this be a warning to you. If you own a smaller board and/or the northbridge is really close to the socket, do NOT buy this cooler.
Just as a reference shot, here is how the TAK clears the northbridge cooler. Now, it seems that I am bashing the H2Twin. I have no intention of doing so. I just would like the reading population to know of the possible risks associated with this cooler and it's possible problems in YOUR case. Now with that said, on to the results...
Now, how did these coolers perform, let's find out...
Duron 800 @ 800
Fairly decent results with both coolers being within 3.5 degrees. Let's fire up prime95 and torture it a bit shall we =).
The H2T has gained a bit here with it's ability to diminish heat better at higher load conditions. How about we do a moderate overclock on the Duron 800 and push it up to 1Ghz and see how the temperatures hold.
Now, with the overclock in place and everything is stable you can notice that the idle temps are pretty well the same as the full-load temperature while at 800Mhz. Let's give it the real test and fire up prime95.
Here is where David beats Goliath, the TAK pulls away with the official win in my books. The H2T stop working well at full load at 42 degrees at prime95 shut down due to errors. Now this could be due to the fact that the fan was off of the northbridge cooler during the testing of this cooler, or, it could be a sign of instability due to the higher temperatures. But I'll let you make that decision...
