I have an i5 2400 and when i play sc2 and my cpu is at load, one of the cores gets to about 75-80c(other ones are in the 60s iirc). I haven't really had any issues or anything but is that too hot? I'm thinking my heat sink might be dusty since I never cleaned it.

yeah thats a bit hot. If its on the one core that might be a defective CPU. Usually those are made into I3's

the reason that the one core is hotter than the others is because that one is stressed the most(at idle, its the same temp as the others). do you think cleaning out the heat sink could help?

is there a way to clean it without removing the heatsink? I don't want to have to buy and apply more thermal plaste.

Do you want to damage your CPU and have to pay ~$160 for a new one or do you want to buy some $5 thermal paste that is easily applied? up to you buddy.

I'm somewhat sure that all dual core i3 ever sold are dual core dies, not quad cores with disabled cores (and disabled furthermore, disabled L3 cache). With socket 1156, the quad cores were 45nm while the dual cores were 32nm. There are separate dual core designs for socket 1155 Sandy Bridge, and I don't think there are exceptions like the rare Phenom II X4 that are actually Thubans (the hex core) with disabled parts.

75-80°C are absolutly fine! A CPU can handle ~95-100°C.

Lol please don't make such posts, there is a big difference between "can" and "should" 70-75 degrees during load is normal, higher is not ok.

This is blatantly wrong. CPUs absolutely cannot handle those temperatures. Some GPUs can, but that is running hot even for them.

According to this the max operating temperature for your CPU is 72.6C. Ideally, you'd want it a fair bit lower than that when your processor is under load.

seems like a badly seated cpu cooler, get an aftermarket cooler (even better temps than the amazing stock cooler) and seat it correctly...

I'll 2nd that. I have a scythe yasya (? i think xD) aftermarket cooler and the things beast. After 9 months without me dusting (i know i know, im waiting on new parts before doing it.) it still sits at 42-45oC under heavy load. (3+ hours of constant battlefield3) this is on an i5-2500k but still, aftermarket coolers are the shizzle! Also good heatsink paste helps a bit, make sure its seated properly, air bubbles are bad.

That temperature is at the upper end of what's acceptable but it's still fine fine. So long as they dont stay like that 24/7 you will be alright.

Ps. Don't get an aftermarket cooler unless ur going to overclock.

One core is always hotter, not that much hotter tho. You fucked up the tim. Pull it out clean it and apply a high quality tim properly. there's an art to it. It's like dancing, less is more. You are trying to fill in microscopic imperfections on the surface of the cpu and heatsink. Too much and it cooks, too little and it cooks.

For reference my I7 2600k is overclocked to 4.8 and peaks at 72 degrees under 24hour torture testing with stock cooling. Sandy can handle that temp. It's all about your thermal paste application.
Nice guys finish last

lol are you sure this is stock cooling ? I have 2600k at 4.7 and with 212+ cooler i get arround 75 degrees after 18 hours of stress testing, but stock cooling ?

Yeah I find that hard to believe too. I have my 2600k OC'd to 4.5 with a 212+. My temps are probably 70ish, but I would periodically get crashes and stalls if I OC'd past 4.6.

It turns out my heatsink had way too much dust in it. After cleaning it out, it doesn't go past 50c at load. How often should you clean the inside of your pc?

That obviously depends on the airflow, whether your case has dust filters, where you put your PC, whether you have pets, whether you are a smoker or have smokers, and so on...
