High temps even after lapping

Inazuma · 8 Mar 2008 at 18:39

The above are my idle temps. Bit high yes? 20C higher than they should be? At full load they reach 70C. I have even lapped the CPU and heatsink (Noctua NH-U12F with Sharkoon 1000), which gave a 5C decrease in idle temps. I use Arctic Silver 5. My room temperature is 21C.

I have one Sharkoon 2000 120mm for inflow and two 80mm fans for outflow. My 8800GTX blocks air flow from between it and the HDD racks, but theres still an adequate gap between the 8800 and side panel. My case is the Coolermaster Praetorian by the way (my front panel is open).

So any ideas?

Considering the overclock , i certainly would not say 20 degress too high.

Not too bad for idle , 45 degrees on air , imo.

Would probably be looking for low/mid 60s' at load , but 70 degrees is not a killer by any means.

Well that's a bit of a relief. How much more should the temps drop once the AS5 settles?
Also, CPU-z shows the Core Voltage as 1.344v (which decreases a little on full load), yet in the BIOS I have set it to 1.415v. What gives? :S

Its called VDrop or VDroop ( one of the 2 ! ) prefectly normal.

My mobo ( Asus Maximus Formula SE ) loses .8 volt between BIOS and Windows.

Nothing to worry about.

Have you tried to lower the CPU voltrage, will it work with lower volts?

I only ask as I have a Q6600 also and upto 3Ghz o/clock on stock volts (1.22 I think).

Less power, less heat

psychas · 8 Mar 2008 at 19:27

36 thats what i get on 3.6ghz idle on q6600 using anrec 900 zalman 9700 and mx2 thermal paste i think my temps got even
36 lower as thermal paste is settled now
27
27

idle on air i think i get even lower now as my thermal paste settled and i lowered my voltage even lower maybe you got bad chip or your cooler is not placed right try replacing it, maybe use bit less of thermal paste.

His chip has a VID of 1.2625 , slightly hotter than some.

Whats your VID ? You must have a nice cool one

Core temp says I have a VID of 1.2375, not sure what this means?

At moment on idle i'm getting 31,31,28,30 (room is quite warm at the moment)

Is this the norm for most people?

Also, since there is quite a vdroop, should I be considering the vcore in the BIOS or Windows when optimising the FSB/voltage?

Space Monkey · 8 Mar 2008 at 20:20

I originally upped my voltage by 1 notch but someone mentioned to me (in a different forum) that they got to 3ghz without upping any voltages to the CPU, so i reduced it back down to stock volts and all is fine, and Prime stable

Nice temps for 3ghz air.

What voltage are you using in BIOS and what voltage is showing in Windows ?

Just curiousity on my part , don't go to any effort to find out.

Just go to BIOS and reduce your voltages as little at a time until it doesn't boot anymore.

Won't do any harm.

Inazuma · 8 Mar 2008 at 20:39

Alright, but I seem to get BSODs while stress testing if my vcore is too low.

Geh, this is quite the ****take

I just reapplied thermal paste thinking I didn't put on enough last time, but the temps are actually higher now.

Hi Mark,

Think Ive fiqured out the VID thing, its the required voltage to the CPU upon booting and general running?

So my BIOS reads the voltage as 1.2375v stock, but varies between 1.20v - 1.21v on the monitoring tab.

CPU-z shows my Core Voltage fluctuating between 1.20v - 1.22v (same as uGuru which reads from the BIOS anyway)

IAmATeaf · 8 Mar 2008 at 21:56

I run my Q6600 at 3.2, it also has a VID of 1.2625, I run it at 1.3v BIOS, 1.264v reported by CPU-Z and my load temps running prime95 are 63,63,60,60 so for the volts your temps aren't that bad.

Yep , you've got a good chip there.

Damn , yours is even better

.

That one should clock nicely.

There are only marginal differences in the VID of chips.

~ 1.25 would be average ( like mine ) below is nice.

Thats a great OC. I can't get pass 379*9 (3.4) and my temps reached 67 using Prime for 8 Hours at load. If i lower the Vcore anymore, i get BSOD. My VID is 1.3125v (Crap chip i guess). Idle temps is around 39.
