Please Help!! CPU Temp off the charts!!

Notorious Lee · 19 May 2007 at 19:47

I have just finished building my PC & had it running now for about 2 hours & messing around in the BIOS.

I have just noticed that it is showing my CPU temp is at 87 degrees C.

Please any advice would be appreciated.

It's an Intel quad core processor.

The motherboard is an Asus P5N32E-SLi.

I haven't touched any overclocking settings at all.

I have just taken off the heatsink & fan which came with the CPU.

There was already thermal paste on the bottom of the heatsink so I have just seated it on top of the cpu & pushed down the 4 connectors securing it into place so it doesn't budge.

The fan is connected to the cpu fan connector as instrucetd.

Do you think the readings could be incorrect?

Notorious Lee · 19 May 2007 at 20:49

It's in the Bios on the motherboard where you can monitor the motherboard & cpu temps.

I took off the heatsink & took out the cpu to make sure it was seated correctly & there are no scratches or anything else.

It doesn't loke concave. It looks fine.

I have now put the cpu back in & replaced the heatsink & fan.

However, when I now turn on the system & enter the bios within a few seconds it turns itself off.

No. Should I?

Notorious Lee · 19 May 2007 at 22:18

Also, if i am re-applying thermal paste do I need to clean the existing paste off both the heatsink & cpu first?

Notorious Lee · 19 May 2007 at 22:29

Now my machine keeps turning itself off I am now concerned the cpu is damaged as 86 degrees is hot.

Notorious Lee · 19 May 2007 at 22:38

How will I know now if I have a damaged cpu?

Also, I am now thinking of buying a new heatsink & fan tomorrow & fitting that?

Notorious Lee · 19 May 2007 at 22:43

But like Servo said I can only imagine it's a faulty heatsink.

Or do you think that the default settings on the motherboard are over the top as mentioned earlier as what should be the correct settings?

Notorious Lee · 19 May 2007 at 22:54

I can only presume it's turning itself off because the cpu is getting too hot.

What I am going to do tomorrow is buy the Arctic freezer pro heatsink & fan & clean off the thermal paste which is already on the cpu & re-apply then fit the new heatsink & fan.

If I still have a problem then my only other option would be to return the cpu under warranty.

Any other recommendations?

Notorious Lee · 19 May 2007 at 23:17

Are you using the original heat sink & fan you get with the quad?

Notorious Lee · 19 May 2007 at 23:21

You see this is why I think I may have a faulty heatsink because just be re-applying a new paste surely won't bring my temps down by 60 degrees?

Notorious Lee · 20 May 2007 at 10:52

Just purchased the Freezer 7 Pro heatsink & fan so I will let you know how I get on once installed.

Notorious Lee · 20 May 2007 at 13:43

Just installed the Freezer Pro & had my pc running in bios now for over 1 hour.

The temps have dropped to: -

54 degrees CPU
54 degrees Motherboard.

Do these figures still seem high considering it's a quad core?

I think they are as I am concerned that once I start using the processor the temps will shoot up.

Notorious Lee · 20 May 2007 at 14:05

The fans I have installed are one from the Corsair PSU which is pointing down.
a fan at the rear of the case to expell hot air. 1 fan at the front to bring in cool air. Obviously, the cpu heatsink & fan & a fan on the gpu.

On the fan control in the bios the cpu fan control has an option of q-fan.

What is this & should this be selected?

Notorious Lee · 20 May 2007 at 15:48

I have got the temps down even further now to: -

Mobo:40 degrees
CPU: 42 degrees

I know what your all gonna say under your breaths & I don't blame you because I am a muppet even for a beginner.

I had the heat sink on the wrong way round so it was blowing the hot air back into the system on the new freezer pro & purchased today.

I re-fitted it but first of all applied fresh paste & at the mo it's sitting on 42 degrees.

Do you think this is ok?

Notorious Lee · 20 May 2007 at 16:07

Do you think 42 degress is acceptable though?

Notorious Lee · 20 May 2007 at 21:22

Just installed windows vista premium & the temp software i got with the motherboard is reading the cpu temp @ 32 degrees.

I am relieved & want to thank you all for your advice.

Thanks.
