Major temp drop.

[paulstung]

I have spent the day moving my room around, and now my desk is at other end of the wall. but after switching my rig on I am seeing a temp drop at idle of around 12 degrees. before I was sitting around and average of 27 degrees and now I'm averaging 15 degrees. That's an i5 4670 @ 4.2 on 1.015v and a pair of 7950's.

The only thing I can think of, is there must have been an air bubble trapped somewhere ? I'm sure that it was bled out, is there anything that could have caused this temp drop ? I'm going to put it under some load now and see if it shows the same result.



So I let OCCT run for about 20 mins and the temps under load are seeing the same result. It must have been a buble.

That's weird, I've never seen an ambient temp that low. What are you running for cooling?

Weird, on my 950 1.325v 4.35ghz I am sitting on 28C -30C idle /52.5C core average. Have to say those temps are really nice.

Iv'e got a monsta 420 and an st30 360 both running push pull with Akasa viper 120/140 fans, all on 5v.

I've got my heating on now and my ambient temp is 23 degrees, and my average temp as I'm typing is ranging from 19 to 24. Something has to be way off. I'm going to try HM and core temp in the morning, see what is going on.

Nice, I struggle to keep the idle temps down, currently I am running between 5-6C difference. The 480mm has 4x Noiseblocker fans on it 1500 rpm and the ax 360 push pull with sp120s but it's really frustrating as I kept changing from paste to paste without and degree difference.

Back to your post I think something is definitely wrong as your reading are going below the ambient temperatures.

Iv'e just installed core temp and hardware monitor, they are not showing the temps as low but only a 5 degree difference. The thing is all 3 are reading different temps, so I'm not sure which one to follow. My gut tells me HM, is the most reliable, any ideas on which one to stick with ?

I don't know, I only have OCCT installed on mine so when I put a H100i in at the weekend, I just checked the temps within that. They must be pretty rock solid accurate otherwise Tom wouldn't be using it to OC.

I'm not sure either. I didn't want to rain on the parade, but those temps did sound too good to be true. But hey even with the 5 degree differential, they're still great. What TIM did you use?

Good old NTH1 mate.

 

[Dicehunter]

My only conclusion ? Wizardry !!! ^_^

Does OCCT display same temps as RealTemp?
Have you manually set Vcore?
Are you letting fans run at full speed?
Is pump working correctly?
Anymore air bubbles?

This is what I'd check next

 

[paulstung]

OCCT, RealTemp, CoreTemp and Hardware monitor all show different results.
All OC settings are put in manually
Fans are at 7v ( was 5v but some had trouble starting )
Pump is running fine
No air bubbles at all.

the only program that was showing extremely low temps, was RealTemp, all the others although showed different results, all displayed more realistic temps, all were around the 25 mark at idle and the maximum being 44 after an half an hour run through OCCT.

Even though the temps aren't as low as RealTemp was showing, they are still at an acceptable level. The temps being bellow 20 was a bit unrealistic really, you could never get bellow ambient.

Right so after a few days of settling down my temps have chilled. With all 3 programs giving different readings, I decided to go with the middle option, which makes sense to me.

so at idle with an ambient of 23 degrees I'm seeing highs of, 31, 28, 28, 27.

And lows of 28, 26, 25, 24.

And under prime for half an hour the maximum that was reached was 43

That's an i5 @ 4.2 with 1.015v, and a pair of HD 7950's. So over all I'm pretty chuffed, I just need to nerd up some more on overclocking to push her ( Gina ) some more

That voltage makes me jealous! My 3820 needs 1.265v to run at 4.3ghz.
