BleepingComputer.com: CPU heat and bottleneck question.

So my CPU(i7-2600 locked) while idle is pretty wild. Using Real Temp 3.60 the four cores are constantly going up and down by 3-10c degrees. The sensor on Asus Fan Expert stays pretty much at 32 degrees. But using Real Temp it'll go from 32c up to 36 to 27 to 42 degrees every other second. The 3rd and 4th core are the only ones that really go down in the 20's. I use a Zalman cnps9900 at 100% all the time and all my case fans are on 100%(Antec 1200). I ran Prime95 for about 15 minutes and the temps were in the upper 50's. Remember all my fans are on full blast if they weren't I'm sure the CPU temps would have gotten into the 80's. As soon as I stopped Prime95 the temp. readings on both RealTemp and Asus Fan Expert dropped from 57c to 34c in a second or less. I would think that
the temps would drop slowly not just jump down 20c degrees in a half second. Are all these things I've mentioned normal?

My second question is would my processor, my PSU(850w), and my MB(Asus P8P67 Pro), handle another gtx460 in SLi mode or would they bottleneck each other somehow? Would this raise my CPU temps? My GPU stays at 25c degrees idle and 60c degrees at full load using MSI Kombustor. My MB seems to constantly stay at 25c. So if you could give me advice/opinions I'd appreciate it. Thanks.

Can you please post a screenshot of HWMonitor when the computer is idle and at full load? Yes you could run SLI also what case do have and how many fans do you have in it?

Yes. A good cooler will drop temps that fast.

SLI is no problem, (assuming your 850 watt PSU isn't a POS). Running SLI your PCIEX16 slots drop to 8X each. That is not a concern as you still have plenty of bandwidth. I think there might be a 1-2% hit, unnoticeable compared to the overhead from SLI itself.

I don't think there would be a problem if you slacked off those fans a little. Your temps are already on the low side. If the noise doesn't bother you, more power to you. I know that Zalman cooler is one of the louder ones out there.

The temperatures look all fine, your cooler is doing a good job.
