High temps.

fobose · 25 Mar 2009 at 23:15

I setup my HTPC today, Asus P5Q-EM and a E5200 with a passive scythe ninja (using MX-2 thermal paste). I thought I best check the temps in windows (bios reads 23.5c), and in everest 4.60 and coretemp 0.99.4 my temps seem a little high.

Everest:

CPU: 23c
Core 1: 55 idle (doesn't change when watching 1080p)
Core 2: 37 idle (41 when watching 1080p)

Core Temp:

Core 0: 55 (doesn't change when watching 1080p)
Core 1: 37 (41 when watching 1080p)

Is it possible that the first temp in each app is just stuck at 55c? Should I be worried?

If I watch the same 1080p on my main PC (E6750 w/ arctic freezer 7), both my cores in everest change from 32-33c to about 42c.

id try reseating the heatsink and thermal paste if i were you

Looks like you've got a stuck sensor, which unfortunately you can't do anything to fix.

One thing you might be able to try...the sensors have a minimum range which is not below 50, so if you get past 50 degrees, you might be able to 'unstick' it. Worth a shot maybe.

Cheers guys. I had considered reseating the heatsink (but would rather not!!). I will run everests torture test when I get home from work and see if that budges the other sensor.

One of my cores never drop below 47 while the other will be at around 30, So thinking dodgy sensor

If running everest torture test doesn't do anything, I think I will remove the heatsink and clear the thermal paste and put some more stuff down, and use a freezer bag to spread it over the core evenly, rather than the "line" technique.

I tell thee I am not looking forward to removing the mini minja with the mobo still in the case (too much effort to remove the mobo from case).

If it's a stuck sensor, like I think it is, then your thermal paste application won't do anything to solve it lol. Just assume that your cores are within a degree or two of eachother under when stressed evenly, and you can still effectively monitor your temperatures...

I kinda just wanted to rule out the heatsink being an issue though. I haven't bothered to take it off as I have ran everest staibilty test for 15mins, the core that does changed didn't go above 45c, the other stayed at 55c. I am gonna let it run for an hour or too now just to see what sort of temp it will get to in my HTPC case.

Thanks again for your help

Here are some pics of my HTPC (sitting on other desk atm waiting to go under TV):

Installed the 4 pin CPU power cable under the motherboard to keep it out of harms way!
