Software to measure negative/sub zero temperatures

[Mr. Smith]

I managed to get my rig running last night before being convinced to go out.

Upon my return I opened Core temp which read 8 deg C.

nVidia read the gfx card at 45 deg C, that is about ~12 deg C hotter than before I had a pelt!

Anyway, the good man that is XMS advised me the BIOS will pick up the neg temps, however, is there any software I can get so I can do this in windows?

Is your gfx card in the water loop? If so, I'm not surprised, those things dump massive heat

Speedfan might work for ya? But as for Asus Probe and Coretemp, neither of em go into the negatives

I was thinking about this...

Take the gfx card out and stick it on air for now, get a bigger case and get a second loop for my gfx card.

Do you think it is worth getting a tripple rad just for the pelt/cpu?

Mine seemed to run fine with a double rad, but I guess the only sure-fire way to tell is if you unplumb your GFX from the loop, stick a probe in the water and see if the temperature stays in parallel with your ambient, or if it rises through the day.

If its that much hotter, then your waterloop is too small. Very little heat is added or removed on any one pass through the loop, so 12C is huge.

Keep the loop the same and get another 2x120mm rad.

The massive heat increase is due to the 320w pelt - before temps were low, now they are high...

My current loop is -

Res > Pump > Double Rad > CPU(pelt) > Single Rad > GPU > Res

I doubt the pump (ddc ultra) could handle the switch to another double rad, or can it?

I'm getting a bigger case so I have options. I want the best performance.

I thought 2 loops would be the answer - cheapest too - someone has a bargain pump res combo for sale too so that would be all I need as I have everything else. (cpu/double rad in loop 1, gpu/single rad in loop 2).

Or I can expand my one loop (if the pump can cope) by getting a tripple rad for the cpu/pelt

Or keeping the double on the cpu and replacing the gpu's single for a double rad (as suggested by NoL).

I was looking at pa120.3 coupled with a pa120.1, or the xspc tripple and single rad, or now it could be 2 double rads... bah.

Tonight I am taking the gpu out of the loop as I need to clean the loop anyway and I will see what happens then.

Just a little update - it seems 8 deg C is the lowest temp core temp reads.

In the bios at start up it leveled off at -19 deg C. (@ 3.0ghz stock volts)

After 2 odd hours of benching, gaming, orthos/occt here and there, temps had settled at -2 deg C. (upped the oc to 3.2 stock, tiny increase on stock volts)

After 4 hours it had climbed to +1.5 deg C so I backed down to 3ghz on stock v's...

I think I will take the gfx card out of the loop as soon as i can be azzed, this should give me headroom for OC'ing whilst remaining < 0 deg C

Winner! I'll try that tonight - thank you!
