High Temps with E4300

[s1m0n]

Hello there,

I have a problem with my Mugen. I've got high temps with an e4300.
It's overclocked at 3ghz. With an Vcore 1,38V. But the temps are too high for a Mugen.

Here are some screens:

temps in idle



temps with prime



CPU Z




I have no idea why the temps are so high because other users in other forums with the Mugen and an e4300 hasn't got so high temps.
I also tried another paste but the temps are still very high.
The fan which is installed at the Mugen is a Scythe Slipstream 1200.

Here are some other datas about my system:
Intel Core 2 Duo E4300@ Scythe Mugen
Gigabyte P35-DS3
nVidia Geforce 8800 GT
2GB DDR 800 OCZ RAM
250 GB HDD
Aerocool I Curve (1 fan at the front, 1 at the back, both are Scythe Slipsteams 1200)

Hope you can help me. Because I dont like high temps.

You should really try to decrease voltage first. 1,38V seems really high even with E4300. Reaching your estimated clock speed with less voltage can dramatically lower your temps.

Especially your idle temps are too high ATM. Are you using pushpins? If yes check if they are installed properly. Also check if Mugen's surface / base plate is totally even in all directions. You could also check the CPU's heatspreader.

But when I take another voltage with another clock speed the temps are nearly the same. And this voltage is the smallest for 3ghz.

No. I'm using the Retention Kit.
What can I do if the Mugen's surface isn't plane ?
Can I change the Mugen or what should I do then ?

[Oli]

This depens on which Mugen you have - copper base plate or nickel plated copper base plate!?

The copper base plate can be lapped while I would not lap the nickel plated version.

The Scythe staff will comment on this next week I'm sure.

[s1m0n]

I think it's a copper plate.
But I'm not sure.
So i can lap it you think ?

[Oli]

If the problems are caused be an uneven base plate and if it is pure copper w/o nickel plating then you could do this:

Please wait for an answer from the Scythe staff before proceeding. When lapping you will loose warranty!

Thanks for this information.
I'll wait until the Scythe Support answers.
Will be better

Hello s1m0n and greetings from Scythe!

First of all please check the distribution of the thermal grease when mounting the Mugen. If you can see, that it is not distributed in a even way, this could be a indication of a surface curvature of your CPU heatspreader or the Mugen Base Plate.

In general, your voltages seems to be really high. How are the temperatures on stock voltage?

Cheers,

I'll check if there's a surface curvature in the next days.

Now I tried to lower the voltage. Because of this I made the clock speed lower too.
Now the e4300 clocks with 2,7ghz with an voltage 1,3V.
And the temps are better now. But not good as well. 65°C with prime...
I think that the CPU oder the Mugen aren't plane.
And of course I have to check whether I have a copper or a nickel back plate

€dit:

So I've checked whether the base plate or the cpu headspreader aren't plane.
Here's the result:

CPU headspreader:



Mugen base plate:





I think the base plate looks damaged. Could this be the reason why the temps are so high ?



2nd €dit:

Today I tested whether the heatpipes become warm with prime. But they don't. They are as warm as my hand. I think they should be warmer when the core temp is 60°C or shouldn't they ?

greetings s1m0n.

[s1m0n]

Hab gerade mal nen Test gemacht. Hab mal den Lüfter weggemacht und passiv laufen lassen. Und siehe da: kein Unterschied zum aktiven Betrieb...
Wie kann das sein ?
Ich hab auch mal an die Heatpipes gefasst. Die werden ühaupt nicht warm.
WLP is drauf. Sollte ja dann eig die Wärme abführen. WLP wurde auch getauscht. Bringt auch nichts...
Zu nem älteren Post: mit Standardspannung wird das Teil genauso warm ....

Hätte gern mal ne Stellungnahme was das evtl sein könnte
