Temp nightmare

[Slinwagh]

Right whatever i do i don't seem to be able to get the idle temp of my CPU below 40'c

So far I have tried:

Scythe Ninja
Noctua UF120
Lapping the CPU
Asus P5B Dlx Wifi, EVGA 680i (Checking for dodgy temp sensor)
Arctic Silver 5
Noctua thermal paste

I have also this week built a similar spec PC with the e6600 and got lower idle temps with the stock cooler!

I am sure I have mounted the coolers correctly, I have done it that many times!

Any ideas it is driving me mad now!

My current case is the Antec P182, previously I had a Silverstone Temjin TJ06 with very similar results.

That's the one with the CPU wind tunnel isn't it?

You could just have a hot chip. Some do run quite toasty!

gt

Yeah thats the one, I have tried pretty much everything other than water!

Concave IHS imo

I have lapped it.

its just a hot chip i would guess.

on average (atleast it used to be like this) hotter transistors = faster transistors! 40c is pretty cold anyway. worry not

Im not worried, its just a tad annoying to say the least!

 

[Slinwagh]

done all you can imo, decent coolers and lapped just aint gonna happen

could always see if you could borrow the chip that you setup on the stock cooler and see what it runs like on u're setup

So new chip or watercooling !?!?!?

Right before I pulled the side of the case the temperature was 37'c. With the side of the temperature is now at 31'c

It would appear that there is now an issue with air flow. The Noctua fan is blowing air through the heatsink towards the roof of the case, bottom to top.

In the roof of the case there there is the fan pulling air out along with a fan pulling air out of the case from the rear behind the CPU.

How can I go about improving the airflow?

Orthos has been running for 25 minutes now and the temperature hasn't got above 40'c

I have the Notcua heatsink on now.
