Is my cpu running really hot? (core temp screenshot attached)

I ran blend test on prime95, and the screenshot shows maximum temperature reached during the tests.. I wanted to know if these temps are really bad, so bad that i should search for a cooling solution..



P.S., I think i should say about the background..I got this PC from my dad who was not using this much, and i needed one.. When i tried to play simple games in lowesr detail level(e.g., dirt 3 @720x480 resolution) for half an hour, screen would go black and motherboard would post status code 40, which didnt yield me anything.. twice when i turned on my PC, i was given a message that my PC had shut down because of cpu overheating.. So i thought of updating the bios and screwed up everything..then i reflashed latest bios somehow and brought my pc back to life(yeah i was stupid)..The old problem still persisted.. Yesterday intel desktop control centre revealed my cpu attained a max temperature of 98C.. Today i decided to clean and reapply the cpu thermal compound, and successfully did that..

I am not into overclocking at all, i just like my pc to be problem free..Now this problem of shutting down is gone i think.. i ran NFS shift 2 @720p for 15 minutes, paused it and left it for around 1 and a half hours and played for another 15 minutes and my PC has not shut down unexpectedly..

I read idling temperatures are to be within 40C and small FFTs on Prime95 would take CPU temps to around 80..If u have seen the screenshot above, should I worry?

There are a number of reason of overheating. First of them is obviously the cooler, the second one is a wrong setup on your BIOS, it may have the voltage at AUTO and while it is in turbo mode it applies to much voltage to the chip. The 3rd one is a bad case/wrong fan positioning, and the last one is a faulty PSU that will push incorrect levels of power to the motherboard/processor that will end up with a fried combo.

So 1st off, tell us what PSU is in there, consdering that you already replace the thermal compound what it was? And lastly, how well ventilated is your case?

@horaciopz ok i thought my build details would be displayed here.. but it hasnt been..

i have a 1st gen intel ci7-860, 8gigs ddr3 RAM, Nvidia gefore 9600GT 512MiB GDDR3 card on an Intel DP55KG ATX form factor desktop board..i have a 600W cooler master (model is I think thunder)SMPS, all in a Cooler master elite 330 case. I have 1 case fan mounted at the back and no other additional coolers, stock heat sink of course..I dont say my cabinet is awesomely ventilated, and on the other hand i dont think it is congested also.. I think my CPU's peak power demand is around 400-450W.. About the thermal compound, i think its some solver compound, i don't know the exact name of the make, well its definitely not an arctic silver made product.. I am sure of that.. And bios has been checked at least 10 times and downloaded from intel download centre only..

Thanks

I dont like most Cooler Master PSU, just the Silent Pro series are worthy. So, lets summarize, you dont know anything exactly what you have, or what you applied to your processor, that may be the problem, buy a good brand of thermal paste and mount your cooler properly.

Thanks for your reply @horaciopz. The reseller told me that the thermal compound was a silver based one(i think all that matters is this as far as thermal compound is concerned), and i now think my main problem, i.e., my pc shutting down randomly on playing games, is my video card problem. I guessed this might be a video card problem and unfortunately many nvidia and some XFX branded card owners also had some problems with same symptoms. Prior to this I thought it was something to do with my CPU, and now after changing my CPU's thermal compound, my PC is still shutting down randomly at 10 mins or 20 mins or max 25-30 mins. So now I have decided to install my video card in one of my friends' machine and see if that machine also shuts down like mine. my mobo doesn't have a built in GPU, so have to check using another machine.. Will report back in a while.

P.S., I am thinking of ordering arctic silver or ceramique 2 from ebay..

Alright i figured out why my pc was shutting down unexpectedly.. The GPU heat sink was clogged with dust..removed it and I was good to go.. And after seeing a video on how thermal compound spreads when heatsink is installed, i think I goofed.. i used spreading method and most probably there a lot of air bubbles.. so my temperatures aren't dropping.. I will be redoing it in a while..

Thermal compound tend to decrease 5 to 10 degrees from the best to the worst. So, if you really think that will dramatically lower your temps with a better TIM you are wrong. Please, run CPU-Z while a stress run so we can see what voltage its being applied to your processor. You may end up buying a better cooler. I will recommend you use the dot method.

Not oc'd anything, running stock cooler the one that intel provided with my intel ci7-860 2.8GHz cpu.. My questions are:
1. Can this be due to wrong method of application of thermal paste?
2. Is my cooler alright?
3. Does changing my thermal paste with correct application method solve my problem?
4. Is this because my case is not very well ventilated? Its a cooler master elite 330 mid tower case..
5. Is changing the cooler the only solution for my problem?

Yes its all mounted good.. can this be due to spreading method that i used to reapply the thermal paste?

Actually some methods tend to be better than others but none will give a crucial advantage. If you use the dot, cross or line method will yield different results between different CPUs, but the margin will be again of 2 or 4 degrees celcius, maybe you applied just too much Thermal compound and your heatsink has a broken pin, you really want to tight well your cooler for the best conductivity.

Still I think you can just swap your cooler for one better, most tower coolers from 25 to 40 dollars will be astronomically better than the stock cooler.

Your case is fine, everything looks normal and the processor is just running too hot because there is not a effective way to cool it down properly, I believe.

he has 1 case fan exhausting the heat out of the case...into a cabinet and he's using the stock intel cooler. Seems to explain itself to me.

That is also my idea.. but i have these issues.. first of all I am from India which means I will have to spend about 25% more price than what these products cost in US.. second of all I am afraid that my cabinet would get still more congested as it is already not very spacious.. last thing is that I am saving on an asus gtx 660 dc2 top.. If changing the cooler is the only available solution, I might have to wait..

If you don't get those temperatures under control your not going to have a chip..adding the 660 is going dump even More heat into the case. If I were you I would install as many fans as my case would allow to get the hot air out.

So I conclude that my CPU is really running hot and is abnormal and redoing or changing to a better thermal paste would make a difference of not more than 4C..

So to remove heat, are case fans enough or do I need to change the CPU cooler? I just checked that a corsair h80 or h60 would fit good in my case and are affordable, but i will have to change my PSU also(it all comes to around 630W, and I have 600W PSU).. And if I go with noctua nh-d14 or thermalright sliver arrow, I am afraid my case becomes too much congested.. Which 1 should I go with? case fans or good CPU coolers? I will update this post with a pic of inside of my cabinet in another 10 minutes.

Update: Pic of inside of my case..

I would go with the h80 that will fit nice in there along with a good fan for the front. I would get something that pushes 60+cfm to keep the air flowing inside that case. I would recommend the cougar vortex fans if you can get them. I just put one in my computer and even at 100% I can hardly hear it.

Looking at your image I believe that you just made a mistake instaling the cooler. The little arrow that tells you where to move the pin to release it is pointing where it needs to go to OPEN and release the cooler, while you need to have then in the other way to secure the cooler.

Pay special attention to this video and how this guy install the cooler. You really should install your cooler better because I believe that your cooler is wrong mounted.

Some zip ties to organize those cables will help out, do it. I feel that you dont need an oversize cooler to get down the temperatures of your processor, just a Hyper 212 or something like that will be enough and will be a really substantial improvement.

Thanks a lot.. I will remove the heatsink, redo the thermal paste and mount it properly today and report back if there are any significant temperature drops..

I saw a video which showed spreading method would create lot of air bubbles in the cpu metal cap-thermal paste-heat sink interface.. so i was suspecting that.. Anyway I will be remounting the cooler properly today.. will report back..

Oh well, get an hyper 212 eve and solve your problem, looks like your cooler just cant keep your processor cool enough.

So i should change my cpu cooler...hmm thanks.. I think i m gonna wait for another month and get a corsair h80(h100 wont fit in my case).. Thanks for all your replies, suggestions, and solutions..

Got a noctua nh-d14..wanted to settle it once and for all(lol)..fortunately it "JUST" did fit in my case.. idling temps are 28C, @100% load its around 57C..

P.S., not planning on overclocking..i dont do CPU intensive tasks a lot..and i am very very happy thanks a lot guys..
