Bigger temp diference? What the.... - Overclock.net

JLT_GTI · 03-04-09

Well.. now with my new (thanks to ASUS) mobo GB P-35-DS3L ..i have my E4500 oced to 3Ghz. Also i have now the thermalright bolt-kit wich sits my Coolermaster HyperTX2 nice .

the thing is that before all this i had the cpu oced by a BSEL mod at 2930mhz. In ambient about 21-23º , idle temp was abot 33-35º and after some hours of orthos.. temp usually toped 65º ..

Now with the CPU oced by BIOS and not by BSEL and the cooler fixed by the bolt kit wich puts more pressure and ambient temp at 17-18º idle temp is about 25ºC.. wich is nice and seems logical with the conditions.. but i run orthos and i see the temp go up to 71º in half hour! .. 71!!. The max "continuos" temp acording to Intel is 73,3ºC and the tmax in coretemp is 85..

I dont understood.. why im getting a far lower idle temp of about 10ºC less (with 5ºC less of ambient) but im getting 6ºC more top temp with the same 5ºC less ambient.. this means that in summer when ambient hits probably 24-25-26ºC i could be lookin at tops of near 80ºC

Makes sense to someone or anyone has a theory why this happens? The thermal paste is correctly applied (artic silver 5) and the cooler is quite well fixed

You never mentioned the vcore, what is the current vcore?

If your vcore is the same, try reseating the heatsink. Be sure to use new thermal paste. Clean the chip and heatsink with alcohol and re apply thermal paste. Are you using the same heatsink that you did before?

cs_maan · 03-04-09

Yeah re-seating can do amazing things, I did that today on my sig rig, my temps dramatically dropped...turns out I didn't properly apply it before -_-.. So about 25% (if that) of my CPU was actually touching my cooler, which is bad...

Acording to CPUZ 1,56V

I may try reseating the cooler.. tought the mystry here is why is cooler in idle and hotter in top temp.. if the heatsink is bad seated it should be hoter in idle too.. i had problems with the push pins in the past and when they didnt work properly you noticed fast the CPU idling at 50ºC

One question.. if i have to remove the cooler .. im thinking in reaplyng the BSEL mod .. woudl you guys use the BSEL mod if.. lets say aim for 3.2GHZ? (BSEL starts at 2,93) or should i stick to mobo only settings...

1.56v is very high, lower it.
What speed is you proc running?

Thats a bug in CPUZ, try SpeedFan. My CPUZ says I'm running 1.58 while I'm only running 1.3v on SpeedFan wich I mesured with a multimeter

Or you are just trying to kill you chip. :P

If it is 1.56v, i'm surprised you're not passing 80c!!!

That is very high for air cooling, it would make my watercooling weep a bit inside

Speedfan says:

Vcore1: 1,57
Vcore2: 2,08

Its an E4500, now its running at 3.0ghz (300X10)

Ok..voltages were auto in the bios.. i set manual and set the vcore at 1,45..im runing orthos now..

yesterday it took 30m to get to 71ºC ..lets see now in 30m how hot it gets (and if its stable)

Edit:

Ok.. i ran a quick 35m orthos and temp went up to 55ºC.. i believe i have found the problem..
This night i work night shift.. so i will left the computer orthoing and monitorize it from work to check if its now trully stable.

The funny thing is that voltages were "Auto" in the EP-35-DS3L bios.. so it was the bios who decided to set 1,57V.... weird
