Review for PC Temperatures Part 1: COOLER MASTER RR-H101-22FK-RA

I recently put a new cooling system into my PC rig, it consists of 3 extra case fans and a new heatsync. I am one who is very careful of my temperatures and I like to check them via my bios readings and through applications in Windows 7 (Speedfan). But to those people out there who think they are getting 20C on your core temps, what is the temperature of your room? Room temperature is generally 21-25C and unless you're living in a refrigerator, or have a cooling system other than air, there is no way you can cheat the laws of thermal dynamics.

First up, my new CPU cooler.


Compared to the stock cooler for an AMD Phenom II x4 955, this cooler is a slight upgrade. At a cost of only $15, it seemed worth an attempt to upgrade to something a little beefier for a possible overclock in the future (as of now my CPU is nowhere near being the bottleneck of my rig).

Note: These temperatures are read from Speedfan and not the bios. They are not the calculated Core temperatures Speedfan also gives, but the sensor readings from the board.

Stock HS&F Idle Temps:

Total Change: 3-6C cooler

(stress tested with Starcraft 2 and prime95)

Stock HS&F Average Load Temps:
COOLER MASTER RR-H101-22FK-RA Average Load Temps:

Total Change: 4-8C cooler

So, as you can see there was a small change between the stock heatsync and the new Cooler Master RR-H101. I would say, on average the difference was about 3-4C; which isn't too bad for only a $15 cooler. This particular cooler also doesn't fully cover the top of the larger Phenom II chips, but does fit more snugly on Athlon X2 and other AM2 chips. I would advise spending twice the money on a quality cooler to net you better performance. However, if you're just looking to extend the life of your CPU by shaving off a few degrees, or replacing a dead cooler, this is a nifty upgrade. I have also heard many people complaining about the abilities of the stock AMD Phenom II x6's cooler, and that this was a inexpensive solution to decent temperatures.

Next up for review is the new pride of my case:
The "Scythe DFS123812-3000 "ULTRA KAZE" 120 x 38 mm Case Fan"
