CPU/Mobo Yet another temperature problem

[CA50]

Hi everybody,

I am using E8400 @ 3.0Ghz on a A-bit IP35-pro mobo.

Previously i was using the stock cooler with some local (i think its ceramic one) TIM.

The temps were some ~45c after using the pc for 20-30 minutes.

Today i replaced the stock cooler with an Artic cooler freezer 7 pro, and also replaced the TIM with thermal fusion 400.

But right now the temps are ~ 42-43c after using the pc for 20-30 minutes.

I am confused :S, I heard that the AC cooler is better then the stock one and also i have applied a much better TIM, i was expecting a major temp drop, like 5-7c.

Also does the thermal fusion 400 needs time for setting, like i heard that some TIM requires some time to work effectively, is that same for thermal fusion 400.

Thanks a lot for reading this.

1. Check the airflow. Especially the rear exhaust fan whose non-functioning can easily cause temperature difference of ~ 4C.

2. Also look at the imprint made by the HSF on the CPU die. It should be even and plain.

3. You can measure the evenness of the HSF base using a scale too.

4. Look at the overall case ventilation too.

5. Make sure the Cooler's exhaust's towards the rear exhaust fan like in this link.

Ideally the temps should've been 4-5C lesser.

Is that the lowest vCore it is stable at that speed.

Thanks fro your reply and sorry for the late reply, was busy the whole day.

Replies for you:
1. Mate i have 2x 120mm fans :
one 120mm (40cfm) one below for intake
one 120mm (40cfm) one rear fan for exhaust
one 90mm front intake (cfm unknown)
- i hope this is OK, i have modded my cabby, and added transliterate side panel.
- also my PSU have a fan at the bottom for exhaust

2. Haven't check it yet, as i don't want to remove the cooler again, as installing it is a pure PITA

3. It seems ok to me.

4. -please advice sometime based on above fan placement-

5. Ya mate, checked those pics long before, and i have installed the cooler as done there.

Is that the lowest vCore it is stable at that speed.

Replies for you:
Ya mate, no OC. Have left the voltage section at BIOS at AUTO, and the speed is left at stock.
Why? Is there some problem with the voltage?

Update

I removed the cooler and re-TIMed it completely. The temps dropped by 3-4c
But the BIOS temps are higher by 3-4c :[

Here is a real-temp screeny. Are the temps in safe zone, considering this is winter. Will this be a problem in the summer.

Just Update your BIOS.

^^ LOL dude
A-bit is history these days, and no more BIOS update are available.

BTW i am on a modded BIOS which is actually ver. 18

wow!!!

i was having the same heat problem and it was fixed by just updating the BIOS to the latest version..

Mate IIRC, heating issue can't be solved by BIOS update, but temps reading might change.

@others, any post please

Do not reference the temperatures which the BIOS shows. And see if you can lower the vCore more, EVEN if running at stock. Default settings usually pump in higher vCore -- if your boards permits it. Keep lowering in small increments 0.01v and test for stability, till you hit the wall.

Wall = stability test failing, BSOD, or system hang.

^ mate i checked the BIOS, the lowest vCore voltage 1.25v, can't set below it

Any other suggestion ?

Live with it then........! Your temperatures are fine anyways.
