Heating Things up: Results Time
The 2.4Ghz CPU was lying around here doing nothing so unfortunately I don't have any test results while running on air cooling. However, I presume that temperatures will be between 40 and 58° C @ stock speed using an Alpha Pal and a silent Papst fan since my 2.26Ghz cpu reached these in my system setup.
As usual, I used Hot cpu tester pro
for stressing the system during an extended period of time to achieve 100% CPU load.
Since it was the first time I used this CPU I let it run @ stock speed for a while (approx 1 hour, as for all the test runs) and afterwards I stressed it. See for yourselves:
42 degrees stressed, not bad if you ask me...
After a few reboots for finding the system's maximum stable speed, I reran the test, bare in mind that I had to raise the vcore slightly to 1.65V. It took a little while longer to complete the stressed test-runs, since it was already late at night, so I scheduled HOT CPU Tester Pro to run for 12 hours with the following results:
The results aren't bad at all, 45°C was the maximum temperature reached after such a long time running at 100% stressed. I remembered that in my review of the Koolance Exos
I got the exact same temperature with my PIV 2.26 @ 2.72 gig. However, I did that test with the CPU running @ stock v-core so this could explain a lot!
One thing that certainly is worth mentioning is my own stupidity: Since Xtreme Tek Werkz
was so generous to let me keep the water block, I’m quite happy with its performance, so I decided to use it in my "permanent" rig. However, this system is never finished, so the power supply for the two 120mm fans is kind of "weird" meaning the + and - wires are just put into a molex, without any tape or so to keep them in place. And yes, two nights ago one of my cats decided to fight with those wires and disconnected them. Result, before I discovered this, 28 hours went by and the CPU temperature showed only 50° while idling!
