Help understanding Temperatures

post #1 of 6
Thread Starter 
Hello,

I'm new to overclocking, but also, to good cooling. I replaced my processor awhile back (after I dropped it and bent pins when switching out an old mobo) with an OEM 7750 BE and kept the old 4200+ stock cooler.

Now I can't run folding@home without sending my processor into the 90s.

While I was looking at overDrive's temperature readings, I was abit confused, specially since my mobo manual doesn't tell you what tmp0-2 are.

Here's what I've got:
cpu: 44idle, 60+ under some load
tmp1: 45 almost always
tmp2: 61-90
tmp3: 62-90

If I check bios I see
cpu: 65
system: 45

Could someone please tell me what those temperatures might be referring to?
Which one is more correct? BIOS or Overdrive?

Thanks for your help!!

tmp1 might be the cpu socket temp while the other two tmps measure the temperatures of the actual CPU cores

Hi Blishdot!

In general, tmp1 and tmp2 are higher than what overdrive reports for cpu... they are reported in addition to the cpu temperature which is shown for both cores but is always the same for each core.

might overdrive get the cpu signal wrong? I'm still not sure what to make of the conflict with the temperatures in bios!

Idol temps look ok but anything in the 90c range is bad man. Spend a few bucks and get something better than a stock cooler. 90c=Real Bad!

In general you should trust the results you get in the BIOS. Sometimes a monitoring program will read the wrong sensor. Try downloading speedfan (here) or realtemp (here) and check their results against overdrive.

Hello everyone,

Here are some pictures so you know what I'm up against. temps is the idle temperatures, temps2 is after about 5 minutes of folding@home. All were taken with the side of the case off.

gpu shows that the gpu stays relatively cool in the meantime, actually got to 57 while it was computing... you can also see from the activity trace how long folding at home was running for! Can't imagine what I've been doing to the system when I was playing games etc.

speedfan agrees with overdrive on the temp input labels it seems.

Have a coolerMaster-212 in the mail. If tmp1 and 2 turn out to be on the board, like the chipsets, is that acceptable?
The chipsets on this board don't have fans so the designers seem to think they need much cooling!

I also just noticed the vCore reading! Correct me if I'm wrong, but is that the mobo trying to down-volt the cpu to get the temps down? (it's set to auto vcore) I mean, at least overdrive shows the 1.3v at 1.04 whereas speedfan shows 1.3v ...
