Hello,
I am getting around 68c in BIOS, 30-40c idle and 60-85c when playing World of Warcraft. Which is the main reason I bought his system.

I tried a Prime95 test and the temp was 90c in under 1 minute so I stopped it straight away.

My setup is
Gigabyte GA-H61M-DS2 Intel H61 (REV B3)
Intel Core i5-2500K 3.30GHz
8GB G.Skill RipJawsX (2x4GB) DDR3 1333MHz
Asus GeForce GTX 560Ti DCII/2DI/1GD5 DirectCU II 1024MB GDDR5

The case I have has 1 intake fan on the front. The power supply is mounted at the bottom of the case and there is no exhaust fan at the rear.

I am using stock heatsink and fan and when I installed it I made sure all pins were clicked down fully.

Why our my temperatures so high? and what should I do to reduce them?
 
I have took the side off the case and just turned the machine on after being switched off for well over 2 hours, the idle temp is around 25-30 degrees.

I have just tried the prime95 test again but with the same results reaching 90 degrees after only one minute.
 
Here are the results for the prime95 test i did 5 minutes ago with the side of the case off.

well i would have to say double check all the heatsink pins are properly engaged--gently pull them upwards

without twisting them--they shouldnt move if they are in right

failing that check the cpu voltage when its under load with cpuz in case its auto volting too high

 
It had some greyish strips in it so I assume that was the paste. I have just checked the pins again and they won't budge. I tried pulling them and then pushing them down to make sure they were clicked in.

I have ordered some Arctic Silver 5 and a fan for the rear, I hope the helps.

Do you think its possible that because the motherboard was cheap (£40) the thermal readings are incorrect?

Even when it is operating at 80-90c the system seems stable.

And are my fan speeds ok, they only went to 1900 RPM at 90c
 
its possible its reading the temperatures incorrectly

1900rpm might be the maximum speed--i never use stock heatsinks so dont know

try the artic silver and exhaust fan to see what happens

an after market heatsink may also be an idea once you have an exhaust fan--assuming your case is big enough

the hyper 212 is cheap and very effective
 
I cant find out any where what the max fan speed is, But my girlfriends stepdad says his goes at 2600 when its on 60c so I'm not sure what to think.

I have looked at the hyper 212 and was thinking about getting it but the stock heatsink should be capable of keeping it at the correct temp according to most people and websites I have looked at.

Thanks for the help anyway I will see if the fan and artic silver help
 
First of all, BIOS may show temps about 10 degree higher. Best you check temps with CPUZ. Also you need rear fan. 2500k average idle temps between 30 and 40 degree. Load should be around 60, if OCed and using after market fan, it can be 70.
 
The heatsink is definitively the problem. How do I know? Your gpu and hdd have good temps but there should be no reason why the cpu is idling that much higher. I'm currently 33-38C on cpu vs 31C gpu/hdd idling. The pins may feel they are in all the way but it's good to check the backside to see if the pins are all the way in. It's very common for people to think it's on correctly when it's actually not. The stock hsf will hit around 70C at full load. The bios will show higher temps because the cpu doesn't idle til it gets into windows.

Cpuz is getting an incorrect vcore reading which is common on gigabyte SB chipsets, you need to use the gigabyte software but I've never seen incorrect core temp readings for any SB cpu or mobo.
 
Im on around 38C and load is around 2-5%. Just google chrome open. I have just been playing WoW and was on about 60c most of the time. 2 of the cores hit max 80C whilst playing and the load was about 80% and 95% on the 2 cores that hit 80C

These load temps worry me the most, am I damaging my CPU even for the short time I was on the game?

In regards to the fan, im sure the white prongs came out the back of the motherboard when I installed it because I checked them.

It feels like the motherboard will snap if I pushed the pins down any more so I guess i will have to take the mother board out and put it on a better surface and double check the back of it.
 
There is definitely a issue with the way the cooler was placed, I would order some artic silver also its very cheap.

The Cooler Master Sickleflow fan and Arctic Silver 5 have just arrived. I have installed the fan and thought I would test the temps again before taking everything apart and applying the thermal paste.

These are the idle results.

Here are the results of the Prime95 test after only 2 minutes.

Do you think I will defiantly have to apply the Arctic Silver 5 or are these temperatures ok?

 
Way too high on load. When running prime95 with my 2600k oc to 4.2 i barely hit 60c. And ive got the same cooler and thermal paste.
 
yes for sure, i believe the safe zone for those chips is 75c. If you're going over, you're gonna damage the processor.
 

It's weird that your idle temps are that low and load temps are that high. Although I've seen this before when another person didn't have their hsf on all the way. Apply the new thermal paste. Prime can be safe to go to 80C since it's an unrealistic stressful workload but intel rates the tcase at 72.6C which I use for normal operation safe temps.
 
I have just applied the thermal paste. I followed the step by step instructions and the instructions for placing the HSF on. Idle temps are ok again but the CPU gets to 80C and the Cores get to 90C in a matter of seconds on Prime 95 🙁
 
Try another temp monitoring software, although I doubt that is the issue, but it's good to have comparisons. Your mobo isn't warped and the hsf is fine? The thermal paste appeared to be evenly spread? I know it's unlikely that these are the issue but just covering all the bases. What are your temps during gaming? You may just need to get an aftermarket hsf to solve this temp issue.
