Too Hot?

[aaronjbc123]

I just put a new build together, Gigabyte P35 mobo, and an Intel E6750. I installed the heatsink it came with, and everything seems to be working fine.

When I load up coretemp or HWMonitor, I see that each core is about 50celsius, at idle, all I have open is this window right now and mozilla. I'm pretty sure this is too much? I was just installing a game and it went up to about 65 or 70. Should I buy a new CPU cooler? I think the stock one is not good.

Also, it came pre-applied with thermal grease, how exactly would I go about removing it from the CPU and from the heatsink fan. Please don't say you can use A, B, or C or A and B and C or A, please just say exactly what I need for that, I've looked around on google and the like and see alot of different answers.

Thank you advance.

I would say that 65 is the safe upper limit...most of the newer cores have an upper thermal of 72.

For you I think you are ok, but an aftermarket cooler will drop it down some and give you peace of mind...especially if you want to OC that beast.

EDIT: I didn't see that you were sitting at 50 at idle...way too high! As already stated, check you heatsink. What program are u using to check temps? Some can be way off.

I'm not super tech savvy, but that number just seems way too high to be normal. A stock heatsink should definitely be at least below 40 C.

I just built a system using an e2180 and a cheap heatsink comparable to a stock heatsink; my idle temps are about 25 C.
The only thing I did differently from you was use a different thermal compound (I used arctic silver 5 but either that or mx-2 are great brands).

I would suggest wiping both the surfaces of the heatsink and CPU with a paper towel to get the old grease off, then using rubbing alcohol on each surface as a cleaning agent and wiping with a coffee filter, and apply a different kind of thermal compound.

The thing that bothers me is that just changing thermal grease isn't a reason for temps to drop more than 10 C, which yours would need to do since it's already at 50 C.

Make sure the heatsink pushpins are all the way through and that they are 'locked' in position, in other words they're not moving up and down. 50C is way high for idle temperature at stock. You do have at least an exhaust fan in your case? The thermal grease and the stock cooler aren't the best but they aren't THAT bad, there's obviously something wrong.

This would be my first guess. That fourth pushpin can be a bear on the Intel heatsink. Make sure that all of your pins on the heatsink are fully locked.

Alright, I think I took it easy on the pins cause it felt like it was bending the board. I only need to twist them to remove them, not to lock them right?

I'm suffering with the same thing. Yesterday I removed the backplate with the motherboard in order to reseat my Arctic Freezer 7 (didn't remove the motherboard from the backplate, though. Thought it wouldn't be necessary).

Although the MB was still attached to the backplate, I could clearly see that all pushpins were in (yes, the last one was a total pain), and they all clicked. Used Arctic Silver just as they say in their website: a thin line in the middle.

But when I turned the thing on again:

Cpu at 2.5ghz (it's a Core2Duo 6600, factory clocked at 2.4)
Vcore at 1.26 (normal vcore: 1.25)
Coretemp reports: 47 per core on idle!!! That's a lot. And I have 4 case fans, all running!

I just don't know what else to do. Could it have anything to do with EIST or C1E? I have them enabled, and Aaronjbc123 may have it too, as it's some bios' default.

Coretemp reports the actual on-die temperatures, which are about 15C higher than what something like speedfan reports. You can read all about it if you google for 'tjunction' and 'tcase' as the keywords.

That said, that's about 10C too high for idle on that cpu at stock voltages & speeds. Something isn't right here. Is the heatsink fan spinning? I don't know much about the Sagitta case, but could it be a pocket of hot air around the CPU?

Did you enable 'automatic voltage control' on that board? I know my gigabyte board instantly cranks the voltage to 1.41 at load if I do that (when downclocked to idle that drops to 1.2). Great for thinking your one in a billion golden E2180 just hit 3.33ghz at stock volts, but not a good thing in all other cases.

 

[legoman666]

I've hit 90C on a Q6600 and it still works.

 

[BadOmen]

Voltage control is on manual, set at 1.26_. (there's a third number here in those decimals that I don't remember). Now, the fan speed control method is actually on Auto. Should it be on PWM? Maybe the fan is sputtering? Although it doesn`t look like it.

The fan is spinning. About a hot air pocket around the CPU... well, the system temps are kinda high too, but I have an internal 80mm fan pointing at my fanless videocard and northbridge, which blows some air on that area. Although, funny enough, my new exhaust fan, an Arctic 120mm, spins but I feel no air coming from behind the case.

As my overclocks are very moderate, I don`t mind heat that much. My only problem: heat = noise, and that I can't stand.

Aaronjbc123, to remove your hs just turn the plugs counter-clockwise and pull them. When seating the hs again, you turn the black part of the pin clockwise (90 degrees should do the trick) before placing it again. Try it a few times before taking it to the motherboard, so you see the very annoying pins working. And I would also remove my motherboard in order to do so.

 

[aaronjbc123]

Oh boy, I'm at 90c just sitting around in Lord of the Rings online with no background programs open. Thanks for the advice, I have time now so I'll open it up.

Ok wow much better. Apparently the HSF wasnt pushed in to the mobo enough, now I'm at about 30c or less idle and 38c or so in LOTRO as before. Thanks everyone.

 

[BadOmen]

Man, I'm praying for such temps. I just cannot go below 47 at idle. And the Arctic was supposed to be better than stock. Rats...

Here is a guide for cleaning and applying Thermal Compound: Guide for proper application of thermal compound.

edit: I'm sorry, I didn't read all the way through to see that you solved your problem.

 

[BadOmen]

Well, I can still use that. Thanks, and thanks v8envy too for your help:thumbsup:

However, Arctic Silver's website recommend a thin line covering the area of the dual core processor. That's what I did. And I also turned the computer on right after eveything was back in place, something around 30 minutes after seating the hs on the cpu.

Does it mean I should go back again and do it all over, now with just a drop of the thing in the middle?

 

[Martimus]

If it is working fine, then I suggest leaving it. Overdoing it is a problem, but if the temps are fine then you probably did an alright job.
