CPU reading super high temps on sc2

Hey TL. I recently bought and built a new computer -- and everything appears to be working fine. When I play league or idle, the cpu seems to be at a good temp (40-50) at idle, and 60-70 on league. However, it seems to rise dramatically to around 100 when i play sc2. I'm going to reseat the fan and heat sinkers and reapply thermal paste, but any other advice would be appreciated. Thanks

40-50 are not good idle temperatures. They should be in the direction of 30 degrees (depending on ambient temperature and air flow in the case). Definitely try reinstalling the heat sink and thermal paste. Make sure you don't use too much, one rice grain sized blob in the middle is plenty. The pressure from the heatsink will spread the paste out.

A quick check you can do is to touch the heatsink when the temperature monitor is showing such high values. If the heatsink is not installed properly, it shouldn't feel very hot (since it's not conducting much heat away from the CPU).

If you go up towards 100 then you really need to do something, 50 at idle is pretty high as well. I wouldn't want to use the computer in such a state. Re-seating is a good idea and if you are overclocking I'd revert to default settings.

I do find it a bit odd that you say it goes to 100 degrees and you don't notice it affecting gameplay. How are you reading the temperatures and can you post your specs as well?

I didn't OC. Yes, the CPU fan is running.

What kind of CPU and what are you using to monitor the temperatures?

If it's a stock Intel HSF, it's probably mismounted. You need to push the pins down really hard.

If you're using your own thermal paste, be careful not to apply too much.

1) 40-50 idle temps is not amazing, but it's not bad either
2) 100C load temps (not even full load) is incredibly bad, as many others have said, you need to reseat your fan, I'm assuming you're using the stock?
3) Do not play until you get this fixed unless you want to run the risk of your CPU dieing/ being severely damaged.
4) Reapply thermal paste, make sure you use a "pea drop" when applying.


Pretty much just mimicking everybody else's words but id say 3 is the most important.

Hey guys, sorry for intruding, but I saw those earlier posts saying that 40-50 is high for an idle temp, and I got a little worried because with my laptop (which I also have a cooling fan for) is around low 50's, sometimes 55 for idle but never goes above 70 under load with any game or process. That being said the airflow (or whatever measure in HWMonitor says) is usually around 27-30. Are these readings accurate and acceptable, or is it even possible to get lower temps with a laptop except for running it in a freezer?

Idle temps don't matter, only load temps do.

As Skyr said, if your load temperatures is under dangerous limits, it's doesn't really matter what the idle temperatures are. Idle temperaturs is more useful as an indication of change in performance (like if you used to be at 30 and suddenly find yourself at 50 etc). Your temperatures aren't great but they are ok for an laptop as they obviously tend to have worse cooling than desktops. You could always try to clean all fans and such as dust tend to clog them up after some time. I know some people put their laptops on fans or cooling pads to get the temperatures down if it starts to get really hot.

Laptops are supposed to be able to live through higher temps than comps.

Thank you for the replies nam and josh :D. I didn't want to freak myself out with the temperatures and have this feeling that every time I use it, it's gonna blow up or something, haha.

You will see signs before your parts are damaged by overheating BSOD, crashes, slow running etc..

Not sure how you are hitting triple digit temps, i always bluescreened at mid 80's to very low 90's when overclocking too far, what CPU are you using?

I use a Noctua NH-D14, it's an absoulutely huge cooler worth £70 on my stock i7-950 @ 3GHz and have around 35-45 degrees idle, so the fact you're getting 40-50 with the intel stock that is far worse than even a £20 CM Hyper 212 or whatever is not so worrying. Load getting to 100 degrees is worrying however. As the guys here have said, can you tell us about your case airflow. Is it the good old unnamed generic case with 1 fan at the back :D ?
And be careful with what your program is telling you are temps. Using RealTemp for example, if you set TJMax to 200 degrees then you'll instantly be told your temps are 100 degrees over what they are meant to be. So be careful with the program (Speedfan also pretty good at telling you the temp of everything).
Can you set a more aggressive fan profile in BIOS?

And to add, I wouldn't worry about temps too too much UNLESS your comp actually shuts itself down. Most CPU's will automatically shut down the comp at 100 degrees, if you don't believe me take off the heatsink and turn on the comp for 15 seconds (But don't put your finger on the CPU, it hurts)

Laptops run a lot hotter because of bad air exhaust. Also, it's kinda stupid to measure idle temps for several reasons. Your ambient temperature is affecting it, so where you live matters. Also, the sensors are only made for measuring correctly at 90C, idle temps are usually VERY FAR from being correct.
I'm taking whatever coverage I can get, because frankly, I'm busy working on this million dollar deal at my job. Early retirement is a good thing brotha man. - MessengerASL

How reliable is RealTemp? Because I'm getting 70 idle and over 95 degrees when playing sc2. I'm using a laptop though.

It's pretty reliable. You can always crosscheck with the dozen other monitoring software available.

your temps are not OK at all, dude i get 25°C on idle, early 40 on load, not oc (i5-2500k)
my load is cooler than your idle? wtf
