core i5 750 temps...

[razer121]

So erm ive got a standered cooler atm (getting a better one in 2 weeks when my clips arrive) but anyway i thought i would observe the temps and by god! what is goin on here? the pc in qeustion has been running for the past 2 hours playing music, i booted into the bios and the temp was 46 degrees...now ive left it for about 15 mins in the bios and it is sat at 53 degrees!!! is there something not that right here or is that normal for the core i5's on the stock heatsink??

p.s - ive noticed an incredible slow down in the pc in the past few weeks do you think maybe i should take the heatsink out and reseat it?

""edit"" the cpu temp is still rising!

Is something putting a workload on the cpu? Reseat the heatsink and check there's nothing running in the background that's using up a lot of processor power.

My 750 was around 24*C at idle and 55*C under normal load with the stock heatsink at stock speeds, sometimes up to 70*C when encoding video (95%+ on all four cores for ten minutes or more). I got a Zalman heatsink and now it's 23*C to 45*C at stock speeds or 55*C overclocked to 3.6GHz.

[razer121]

well the cpu is at stock speeds with stock cooler and now it is sat in the bios (so not doing anything) and is at 56c! i think there is somthing very wrong there lol going to let it cool down for half hour then reseat the heatsink and see how she runs then

You should also check the voltage settings in bios, as some boards default the VTT way too high. IIRC stock QPI/VTT is 1.1v (don't quote me on that, I suggest googling) and from the testing I've done every 0.1v higher adds ~10c.

Sounds like you haven't fitted the cooler properly. Reseat it and make sure all 4 pins are pushed through to the other side of the motherboard properly!

[razer121]

i opened it up....wow its pretty bad one pin is not cliped in! the dust on it is pretty bad...really need a filter on the front lol, i can only guess this has been caused by me moving the pc about, only started to run like a bag of crap when i moved it......will update after i spring clean it

[razer121]

upon reseting the heatsink and giving it a good clean...it now sits at 47 in the bios...still not very happy with that but dont think there is anything else i can do...

[Terbinator]

Still idling at that temperature is actually quite worrying. What case have you got and is it well ventilated? May be worth re-seating the cooler again (give it a good push, the motherboard wont break) other than that try buying a third party heatsink ?

It probably wasn't in correctly when you first fitted it, it can happen, always double dhech the pins from behind the motherboard, you can see when they are correctly locked in, the black central pin will be level/slightly sticking out, from the two outter white pins (that not the correct term but you'll see what I mean if you look at the push pins on the cooler.)

What happens next (as I've found out) is the very wax like thermal compound used by intel melts as it gets hot, and resolidifies when it cools, if the pins are not correctly locked this meltiing and resolidifying of the compound make it work it's way down the cooler and can end up prying it lose.
and leaving only half the cooler contacting the cpu.

EDIT: also have you got the PWM fan control on? and what target temp have you got it set for? I'm not that surprised at 47c if your target is set to say 50c on the rather pants stock cooler.

[razer121]

guys...ive got the stock heatsink and yes its set to 50c for PWM lol maybe i should lower this...

well either way i am getting a aftermarket cooler for it, well ive got it im just waiting for the clips.

not to sure why it gets so hot ive forgotten the name of the case but it has air being pulled in at the front and thrown out at the back...good cooling if you ask me!

[Pob255]

What cooler are you going to use?

[razer121]

Im going to be using a scythe mugen, ive got it now but im awaiting for the clips to arrive so i can mount it,

Mine is about the same as yours tbh. Around 45c at idle, everything at stock. Thought this was normal...

My i7 860 used to idle at around 25c

My i5 750 with a Titan Fenrir @ 3.6 or 3.8 (been about a week since I went on that one, and I keep fiddling) idles at between 24 and 33c and load is near 52c. This is in a room that gets to 21c ambient temp.

It did get to 65c while running Intel burn test on maximum with 50 passes at 4ghz. I thought that was a bit toasty so lowered the OC.

[razer121]

hm so i guess it could be normal? ive got the thermostate set to 22 the board by the way is a msi board, can i just ask what you guys are all using? ive a feeling it could be somthing to do with my mosfets
