hello guys i recently bought a new computer

here are my specs
i5 2500k
z68ma g45 motherboard
4X4gig corsair ram
550w gx series smps
hdd and dvdr

my problem is that the cpu temperature is way too high when i start the system and see the bios temperatures
its about 65c and when the windows is booted up it gets decreased to 50 at idle
even if i use a small program the temperature is getting over 70c
i checked if the heatsink wasnt installed correctly
i even tried applying some thermal paste
and none of them worked
i m using the stock heatsink that comes with the cpu
any ideas ???
need a lot of help
 
^^ Okay here is what you need to do, man -- [thanks for buying Intel by the way]

A basic guide on how TIM works and how to apply it on PC's -- Guide - How TIM Works & How To Apply It Correctly | bit-tech.net.

Also if this does not help, re-seat your CPU heat-sink. I think I've already perpetrated this a lot here but, here goes once more -- Intel stock HSF packages simply put -- SUCK. AMD copper blocks are better [after having smaller fans], albeit noisier.
Here is why -- CPU Cooler Guide For Sandy Bridge!! - Digit Technology Discussion Forum.

So you might think about getting a third party HSF, this'll help you while over-clocking too --

Cooler Master Hyper 212+ ~ 2100/- [frugal, good performance for its price, reliable when put in a push-pull format, not the best tower heatsink out there] -- Cooler Master Hyper 212 Plus CPU Cooler Review
Noctua NH-U12P SE2 ~ 3900/- [great performance, knocks of most entry level closed loop coolers, comes with two fans + great TIM] -- Noctua NH-U12P SE2 CPU Cooler Review - The Noctua NH-U12P SE2 - Legit Reviews
Noctua NH-D14 ~ 4700/- [best in class performance, great TIM and really buy this if you want to push your CPU to the max] -- Noctua NH-D14 CPU Cooler Review.

Hope this helps.
 
OP..bios will show higher temperatures as at bios screen no power saving features have kicked in yet..65C temperature at the BIOS is a little on the higher side though. Typically with ambient temperatures of around 32-34C inside the room, the idle temperatures will be 42-44 C using the stock cooler, so yes again your idle temps are a bit high too. Load temps in excess of 70c is normal with the stock cooler.

Kindly take out the heat-sink. Clean the CPU heatspreader with a lint-free cloth & IPA. Then re-seat the heat-sink -fan but be careful to put equal pressure on all the four push pins such that they click at the same time. Restart the PC and check for temps.

Also like Alpha said, plz invest in a better aftermarket cooler.

For eg: in my case with a i7 2600k (it runs hotter than the i5 2500k) I get the following temps:

At Stock: idle - 35-36 C (windows), bios - 44-46 C , load- 56-57 C (prime 95 blend), Cooler: Spire Thermax Eclipse II, Room Temp: 28-29 C

At 4.5 ghz: idle- 36-37 C (windows), bios - 47-48 C , load - 66-67C (prime 95 blend)

I actually get bios temps of 50"C + as UEFI BIOS will utilize a single core, but once windows loads ups idle temp drops to 38-39"C.

OP: Which cabinet do you have, and is there adequate airflow inside?
 
OP do you have a Cooler Master GX 550W SMPS, that is a bad design released by Cooler Master.
 
^^ look an anemic SMPS cannot power all the components stably and efficiently, generates heat in this process, has a probability will explode and when does this will affect other components too.

This is not a direct precursor to a failed system, but it can be a reason why the system ails and cannot perform as intended. Also the GX line-up of Cooler Master SMPs' were not well received by most enthusiasts, except for the GX 450W which provides stellar performance.

Hope this helps, explain my stance on a bad SMPS.
 
Had a query does SMPS have any effect on the Temeperature ?? .

I am guessing the PSU, blowing in the hot air :P

Agree with all your statements, but am not clear on the bold part. What generates the heat? PSU or the absence of clean power?
 
^^ The SMPS already is under strain to provide power, I'm not sure what is clean power, I assume you mean that the power is unstable and fluctuates wildly, whence this happens, this damages the components.

The SMPS has to take in more power, efficiency is already low this means power is lost to in the process of conversion from AC--DC -- lost to heat. This I think will be the most likely reason that the SMPS blows up.

I think I'm rambling now. Can you please shed light on this.

Thanks Sire.

In that event wouldn't all systems which are powered by no-brand PSU's have heating issues?

BTW you keep stressing on the SMPS "blows" up. AFAIK I have seen very few issues of these, and its largely due to power fluctuations. And its not so much as blowing up, but conking off with black smoke. Blowing up brings images of an explosion with loud boom sound :)

Back to topic, I dont think PSU is the culprit for the heating issue. Although am not too sure of the quality of the SMPS. Try measuring the temps with the side panel open. If the temps are lower, you will need to improve air flow in your unit..
 
i m using cooler master elite371 cabinet

one fan pushing air directly onto the cpu and another on the top blowin outside

i even tried cleaning up the old thermal paste and applyin new one but still nothings workin out it still goin out at 56c and even a smallest game like tekken on emulator is taking the temps to the unimaginable 90++

another thing i had in mind the heatsink is supposed to heat up which thereby cools the cpu tell me if m wrong

but my heatsink never seems to get hot when i just turned system off
 
+1 the psu is not the culprit, most likely its an incorrect installation of the HSF. Op remount the heatsink properly, the fact that your heatsink is cool to toucj indicates that its not making proper contact with the CPU & thus is not able to transfer the heat.

Anyway apart from the efficiency of the PSU (less efficient PSU will just draw more wattage at the wall outlet causing an increase in the power bill), what actually sets apart the good PSUs from the not so good ones, is the power delivery characteristics at different loads. Also the really poor PSUs wont even be able to provide its rated wattage in most cases.

By power delivery characteristics, one refers to the level of ripple & noise. A good PSU will deliver really clean power at very low ripples & noise. The more robust the AC-DC filtering in a PSU design the more likely it will provide good clean power at varying loads.

Thanks Sire, I think I will have to keep researching more on this topic. Thanks for showing the error in my point of view.
 
hey guys here's an image of what my temps are showing out in speed fan and coretemp

can you tell me what temp is what coz am a bit confused see in somany temps

as far as i ve seen the temps the order was cpu on second place

correct me if i m wrong[attachment=10126:16962.attach]

^ mate, can you upload a better resolution picture, nothing is visible in the current picture :(
 
^ the temps seems fine to me.

I suggest you use Core temp / real temp / everest for temp monitoring.
Speedfan temps are not detailed. I left using speedfan for the same reason

i m using all the ones mentioned above but they only show the core temperatures
and all the core temps shown by others are same as others just a variation of millisecond to show them thats all
but is it normal for coretemps to be at 40degs C

tried playing cod and coretemps went up to 58
is it ok???
ie for a new cpu\??
