My CPU is over 100'C when on full load

post #1 of 12
Thread Starter 
Hey guys. I have just built myself a new rig (full setup below in case you need to see everything) and when i was moving my tower to a more suitable place, my stock heatsink fan somehow un-clipped and fell off. I then placed it back on and i found that when running games or any kind of demanding process, it reaches temperatures of around 100'C. The idle temperature is around 35-42'C. Is there anything i can do about this? I am going to try re-applying the thermal paste as well so if you have any tips about that, that would be great smile.gif

SETUP:
i7 950 (Quad core) @3.06GHz
8GB RAM
GTX 570
Asus Rampage III Gene (Micro-ATX)
Cooler Master HAF 922

FANS:
With my case i had 3 built in fans. One at the front, one on the top, and one at the back.
My i7 is using a stock heatsink that came with it. But after it falling off, i think the thermal paste isn't applied properly.

So also is there any other way after applying a new layer or thermal paste, that i can keep my system running as cool as possible?

there is no way youd hit or exceed 100C, your pc would thermal shutdown, if it happened id like to see proof.

re applying thermal paste will somewhat solve the problem, but if aftermarket cooling is a possibility, look into buying a CM Hyper 212+.

Yep, clean off the old stuff, wack on the new stuff... not toooo much and secure that heatsink. Good advice from PC Sarge about looking into something better for a HS.

Prochot occurs around 90c in which case the pc shuts down. Make sure your temps are accurate.

You must have bad temp sensors. This also happened with the Intel E8400s

Um, my 920 has hit 100C and throttled for hours after leaving the door to the room closed with no air coming in.(3 big rigs folding in the room). It was showing 99-101C and throttling up and down like it was designed to do. It was doing this for over 8 hours while at work. Just saying it may not be a bad sensor. It sounds like the heatsink itself came off and not just the fan, or I am reading it wrong and you are trying to say the heatsink. If that is the case, I say you just seated it wrong. You said the stock HS, those pushpins are a pain to get on correctly. I'd say one or more of the pins are not "locked" down right. Of course, you would also need to clean the old thermal grease off and put new on, but I don't think that alone would cause 100C temps. I've had this happen to me in the past, pins not pushed and locked in correctly, very easily done with those pita's.

Happened on my i5 750. On a rebuild one day one of the clips came loose and I didn't notice until after I had assumed the stock heatsync wasn't cutting it and ordered my CM 212+.
Just check all of the pegs once before you decide to blow your money.

Ive had a friends core i5 push 97C with stock heatsink/fan. Those pushpin stock heatsinks are BAD bad bad. You want an aftermarket cooler with a backplate/bracket mounting system. It's a bit of a hassle to mount since u gotta disassemble the whole pc and take motherboard out to install the bracket but its very worth it. The heatsink will be solid against the cpu and never move again. the CM 212 is a good and inexpensive heatsink.

And besides think about it, a low cost purchase to protect your computer such as a decent heatsink goes a long way towards securing the whole investment you made on your pc.

Buying a new HS is in no way blowing money. It's one of the most important parts of any rig, so cheaping out is no way to go. If you buy a cheap HS prepare to spend a lot of time trying to get better temps out of it.

As a lot of other have said, re-seat the HS and you should be fine. There's a chance the pins may have been damaged so check them against known good ones before trusting them to hold that thing on there again.

or you have a rig where you can install the HS without removing the mainboard, also a proper mounting kit is very usefull,
i recommend noctua or thermalright from what i tested so far
