Acceptable CPU Temps & Stress Testing - Page 2

post #11 of 20
I would expect idle to be around 30c. Corsair H100 / H100i have a history of problems too.wC6y

Yes it seems the general feedback is that it's not too high but on the higher side of temps.

Is there any way to get the idle temp down without replacing the H100i? (Is I've just bought and fitted it).

Thanks.

Guess you missed the first sentence

Your CPU is perfectly safe at 65-75c but I will not run mine at higher temperature than Tcase.. and your Tcase is 72.72c. Tcase is "the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).". which is about 10c cooler than core temp.

To monitor Tcase you would need a temperature probe imbedded in the top of the CPU/on bottom of heatsink/cooler.. and this is impractical.

Tcase readings are approximately 8-15c cooler than core temp readings. This means CPU core temp can be approx. 82-83c as a safe operating limit...

to define a good idle temp with specific cooling is impossible, you could run a bad cooler in the artic and have better temps than someone with custom watercool in Australia.

Your temps are fine btw, why not just revert back to stock settings, and overclock it yourself?, or does that void warranty or something.

That's a little heavy handed. rolleyes.gif
By your own logic; .

I think it's fair to assume ambient is in the 19-24c range.. probably more like 21c.. About 30c is what I would expect as an idle temp to to be.

doyll thanks for re-explaining the Tcase info. Zigles - good point on ambients though, I think the room my PC's in is a little warm and the machines quite near a radiator so have turned that down. I'd like to see if I can get the provided OC working first as it's guaranteed and all already configured - if not I could then attempt it myself (although think I need to learn a couple of things on it first) or feed back to the supplier if there are any issues).

having now established that the idles a little high but not the cause of the system crashing when CPUs at 100% I thought I'd up the voltage slightly, unfortunately this didnt really work and caused an error.

Please see the below steps taken (and results):


1. I changed the "CPU Core Voltage" to "Manual Mode". The first thing I found strange was that the "CPU Core Voltage Override" was pre-populated with 1.310 which I assumed was just a default value (higher than what I am looking to set it to) and changed it to 1.125 (as currently my "CPU Core Voltage" is 1.120V).

(click to view)

Set_to_1_215.jpg

2. When I went to save the changes it gave a confirmation to change the override from 1.310 (which I'd never saved previously) to 1.125, so did I actually end up reducing the voltage or is this just an incorrect statement?

3. After saving Windows 8.1 wouldnt boot and i got this error:

Please advise where I may have gone wrong?

try increasing the voltage to 1.215 instead.

Hi midgethulk, thanks for the post.

I tried 1.215 which successfully booted this time but as soon as I ran Prime95 Blend test it crashed (even sooner than usual; previously jt was running for at least 10-20mins).

Do you think it's possible that the 1.310v setting was relevant as it seems to be reducing stability by manually setting voltage at the moment?
post #19 of 20
1.310 seems a bit high to me I'd try upping the voltage to 1.225 then try again. If that doesn't work try 1.250 and so on.
