i7 870 overheating @ stock

post #1 of 13
Thread Starter 
Hello!

Few months ago, I bought an Intel i7 870 processor. When it was new (on less than a month) I kept an eye on the temps and they were fine. They were even great compared to my old CPU. But now, it started overheating. I cleaned it and it was really dirty. But the temps just keep getting higher and higher. Now it runs at around 50 Celsius w/o doing anything on it. And when I start Everest's Stress Testing it gets to a HUGE amount. It runs on stock clocks, stock volts, HT ON. Everything is how it was when I bought it. And it is damn clean! If it's dirty - OK... I could get these temps.. But it is CLEAN! :/ I looked if the FAN doesn't make good contact with the CPU, but I think it's alright! :/ Look at the temps... :/

Thank you!

Have the ambient temperatures gone up quite a bit in the last few months? The stock cooler isn't the greatest, but if it's clean & I can see in everest the fan is running properly I really can't see why the temps are so bad.
When you cleaned it did you remove the heatsink? If you did, did you reapply some thermal paste? You mentioned checking the contact, if you lifted it off the cpu you would need put on new paste for the best contact.

I would check to see if you installed the pushpins right.

Well I don't have any. :/ It's new and it's the first time I actually clean it. :/ But when I was cleaning the old one I didn't have any problems if I don't put thermal paste again. :/ If this one is going to have problems.. lol.. :/ Than I should go and buy one. biggrin.gif But I have never put thermal paste in my life! biggrin.gif Someone has to show me.. But we'll see.. But there WAS thermal paste on it when I put it on! :/ I tough this won't be a problem, because there really was thermal paste... :/

Any other ideas? biggrin.gif

If it was getting decent temps before & you never actually lifted the cooler off the cpu it should be OK, if it was lifted off the cpu to clean it or check it that could make a difference in temps. Old paste gets tacky & reusing it doesn't work very well.
Also as posted above, if you took it out to clean it you should see if the pushpins are all seated properly. I assume it was the stock heatsink & fan that came with the cpu.
Also, when cleaning it out did you clean out all the case fans & make sure there is good airflow through the case?
Ambient temps make a difference as well, where I am it is 15° warmer outside now than it was a few months ago & warmer in the house too with more sunshine, as the temperature warms up the computer will run warmer right along with it.

I don't have any case fans. :/ I keep the case open so it can get some colder air. If I keep it closed the air in it gets very hot. :/ And the temperatures will go to... I don't know... biggrin.gif And can you suggest me a good "Thermal Paste"? And do I have to clean the old one? (If this is even possible... biggrin.gif ) And what happens if I mess up 2 different pastes?

Thermal pastes all perform similarly (within a couple degrees of each other), whatever you can find in the store will be better than nothing (mx-2, mx-3, arctic silver, OCZ freeze, etc.). Might be an idea to get a better cpu heatsink as well, the intel stock heatsinks really aren't that great, chances are really good that getting even a cheapo aftermarket one will cool the cpu better (if a new one doesn't come with a fan you would need that as well).
Doesn't hurt to check what is there & the prices on them at least.

So if I mix 2 different Thermal Pastes I won't have any problems? And by the way, which one of these is better?

I'm sorry for the Bulgarian pages but here prices are different and there isn't a big variety of products. :/ biggrin.gif

What I would try,

0.) Make sure the pins are secured properly, they are a PITA.
1.) Disable HT
2.) Set core voltage to 1.15
3.) Disable turbo / Set manual clocks and disable stepping.
