View Full Version : high temp
Right i been thinking of perhaps having a go at overclocking my pc (beginner at this but u got to start sometime!)
At i been checking my cpu temp and its running at 75 degrees celcious which i believe is too high?
At the moment in my build i have 3 fans operating - 1 which i got for the cpu, 1 built into the power supply and then 1 which is attached to the case.
The problem i have is that i have another fan which is attached to the case but there appears to be no where for it to be plugged into on my motherboard - the power plug on the fan is a white one with 3 pins.
The motherboard i have is a Asus P5GC-MX/1333, i945GC, Socket 775
So is there anyway of powering this fan or shall i buy a different fan? advice would be great thanks!!!
Are you useing the stock cpu cooler? What cpu for starters, and what case?
The cpu is a Intel Pentium Dual Core E2180 2.0GHz (Retail 775), the power supply is a Xilence 480W Gaming PSU and the case is a Akasa Zen Silent-Cool - Black
Thanks for your reply

If that is stock settings then I would suggest that you check the Heatsink is installed correctly.

In what way may it not be installed right? I am getting the temp from the BIOS settings
if you don't make sure the pushpins are down properly then the heatsink wont make a good contact with the cpu and you will get silly high temperatures, such as you are seeing now.

+1 on what mac said ;)
ah got you!!!!!!!!!!! that may be my problem then!!!! what do u think shud be the temp i should be getting then?? your advice is great thank u!!!!

I get 25-30 idle with my e2160 pin modded to 1066 FSB ;) 2.4Ghz but that is with a Freezer 7 Pro
It doesn't go much higher at 3Ghz
i must be doing something wrong! i have taken it off and put it bk on but the pushpins r buggers!!!!!!!!!!!!!!!!!!!!!!!!!! it appears to be tight tho, is this deffo gonna be my prob? shud i think abt a new heatsink?
Was there any thermal paste (sticky grey stuff) on the bottom of the heatsink???
Try reapplying it.
Also what are the volts (Vcore) in the BIOS it might be too high.
hmmmmmmmmmmm paste no dont think so! i will find out the vcore now
Hi,
I'll have a look around for the average VCore, it might be a tad high.
The main proble though is the lack of paste between the CPU and the heatsink/fan (HS&F), it really should be there.
It aids the transfer of heat from the CPU to the HS&F, as neither are exactly flat and you don't want any air trapped either.
Go on your favourite auction site, get some Artic Silver 5, about £4.
i never applied any past myself - i didnt know u had to! at 70 degrees shud i nopt be using my pc?
Yeah you need paste, at 75C i would stop, otherwise big chance of killing CPU. (According to Intel).
Other people have a Vcore as low as 1.2V, however most specs are made up on forums and people just talk crap.
But go into the BIOS and drop the VCore down to 1.3V it should be fine.
Then you can leave it a few hours, play a game or whatever see how it runs, if its fine, drop it down 1 notch at a time.
If you get to 1.25V and its still playing fine then leave it there.
Good luck.

Mines at 1.25V :)
i just download core temp application and the figures on there read for the cpu temperature core#0 and core#1 as 46 degrees celcious is this ok?
Is that at load?? Or is that just looking at the Desktop with no programs running.
As Wonderlust says, as he has similar about 30C should be right at idle.
DId you drop the VCore? Order any Paste??
i have ordered some paste, how do i drop the vcore? it wont allow me to alter figure
that temp of 46 degrees is running no programs just on the internet
Hi, 46C is too high really for idle.
Just from googling your motherboard it seems it has a whole host of problems as most shipped with a 0205 BIOS which was a testing one.
Also it seems that version 2 motherboards have a locked BIOS.
Try and find out what BIOS revision you have, and see if you can Flash it to 0207 and see if that changes the options.
If you don't know what i mean by Flashing the BIOS then i wouldn't bother.
YOu could also try setting default options in the BIOS and see if it helps lower temps as the auto VCore might lower itself, unlikely but worth a shot.

If it turns out to be a locked bios then the only over clocking option is a pin mod.
BUT... Not all Asus boards will work with a pin mod.
My P5K-VM does but a friends P5KPL-VM won't boot with a Pin Mod
I can changed the processer speed in the BIOS so this means it isnt a locked BIOS?
I concur temps are way too high for idle, you should be looking more like 20-30 with your current cooler.
Did each of the 4 pushpins "click" when originally installing it?
Yeah i do believe so i took it off last night, and put it on and all 4 push pins clicked and appear to be tight.
I have bought some thermal compound, can any1 advise me on how to properly use it
I also bought a 3-pin fan splitter so now i have both the 2 case fans working
Thanks again for all the help!
P.S. i dunno if i should admit this but my pc has been running like this for about 1 year now i believe
Hi,
Okay, there are many different theories on how to apply thermal paste.
The best way i personally have found is to draw a thin cross ontop of the CPU, making sure that the two lines start at the top and end at the bottom, same for left to right.
Then place the HS&F onto the CPU, before pushing the pins down give the HS&F a wiggle from left to right a few times, gently.
Also the best method for placing a HS&F that has 4 pushpins is to do opposite corners.
So if the top left is 1 and top right is 2, bottom right is 3, bottom left is 4.
With a flat hand, apply some pressure onto the HS&F, not too much, then press pin 1, then pin 3, then 2, then 4.
This insures that all pins are depressed equally.
Hope this helps.

when you took it off last night was there any paste on there?
no i didnt see any, should the paste be on top of the silver metal case which the cpu is in?

Yeah it should be sandwiched between your cpu and the heatsink.
The method which El Wayneo detailed is probably a bit of overkill, I would recommend you use a single straight line from top to bottom. Like this (http://www.arcticsilver.com/pdf/appinstruct/as5/ins_as5_intel_dual_wcap.pdf).

Are you removing the motherboard when remounting the heatsink.
If not I would highly recommend doing so, it is the ONLY way to ensure that it is fitted correctly.
I'd go for a plump grain of rice size of paste personally LOL
its quite concerning there is none at all on there at the moment though
concur with WL. remove board and sit it on some cardboard on a kitchen worksurface or somewhere flat and sturdy. After applying paste, press the pushpins down in an opposite order ie. 1, 3, 2, 4, press the pins with right hand while you hold the heatsink/fan flush and flat with left hand. The final pushpin no 4, may require a lot of pressure to get the click.
I'd go with all of that too, about taking the motherboard out.
IMO, I dont think it really matters HOW you put the paste on, as long as the cpu surface is covered, and you don't put on too much.
You want the thinnest layer possible. Too much and it can have the opposite effect, act as an insulator and raise temps. Personally, I physically spread it out on the cpu using a pallette knife or some other straight, blunt edge (read, debit card.. :D ). I normally get it to less than 1mm, and it seems to work. I've tried it that way and also the grain of rice/long line way, and i've always got better temps using my way. But only by a couple of degrees, and you need to make sure that you don't scratch the cpu.
I'm not saying there is one better way above another - I'm just saying that there are many different ways, and all work roughly as well as each other as long as you put the correct amount on :)
Well i just whipped the MB out and applied a thin layer of it i didnt use anything to spread it tho i just applied the heatsink on top and clipped in the push pins (3 were easy the last one just didnt seem to want to clip in!!)
I did notice there was paste on the underside of the heatsink but there was a big thin scratch through the middle would this have an effect???
Now on my desktop at idle with nothing open well with just this browser with the core temp application its showing 22degrees celcious! Is this better??
You didn't have the pins all the way in if one was very difficult when you had the mobo out, then it would have been impossible with the mobo in. That was your problem, not thermal compound, but it sounds like you needed a bit to fill the gap created.
Temps are very good now :thumbsup:
Much better :) :thumbsup:

Sounds about right :D
yeah its averaging 25/24 degrees celcious now at idle
when i connect to the internet it goes up to about 34/32 but then drops back down, is this ok?

Ok, my E2160 @ 3Ghz (Freezer 7 Pro PWM set on low 900rpm aprox) with speed step on is idling at 28/30

They're always very difficult, hence the advice to put pressure onto the HS&F when doing the pins.
It isn''t impossible is it? I bet you can do it, i know i can.
Anyway temps are alot better, well done.
Cheers for all the help guys!!!!!!!!

My meaning was that if it was almost impossible for him to push the pin in when the mobo was out of the case then it would have been impossible with it out.
