So I just built my new system, and I'm running (the above cpu) with a CM Hyper 212 EVO, Corsair 230 t case, and an ASUS M5A99X EVO R2.0. I have 2 x 120 mm intakes and a 120 mm exhaust.

The problem started in my BIOS, I was getting temperatures as high as 46-50 C (open case). Then when I got into Windows using CPUID HW Monitor my idle temps were between 41-45 C. I played a game of "League of Legends" and my temps were between 52-60 C. To top it off, I installed "Settlers: Rise of An Empire" and the second I started running it i had this horrifying screeching in my headset, and I took it off to find the screeching coming from my system (but with less intensity as in my headset), I looked at the temps and I was around 56-58 C. What the Hell was that about?

I'm very uncomfortable with this, should I reseat my heat sink and re-apply thermal Paste, maybe more this time? ( I did a tiny pea drop). Should I get better Thermal Paste? Should I install 2 x 140 mms (I have in my possession) at the top of my case, one as intake the other as exhaust? Should I ditch the 212 and get a closed loop? Did I get a bad chip that runs too hot? Any help would be appreciated...

Your temps are supposed to be like that mate, once they get into the high 80's is when you should be concerned but that will only happen if you overclock

Well it definitely wouldn't be a bad idea to reapply the thermal paste but more importantly make sure the heat sink is seated properly. Maybe your pea drop was too big. Remember, the thermal paste is only there to fill in the spaces and imperfections between the heat plate and cpu. And your too mounted fans should both be on exhaust, heat rises. You should have an intake on the side and or front of your case. If you have extra fans sitting around you should always install them anyways lol. The 212 should be sufficient for you

Yeah, I had A LOT of trouble mounting the 212 evo, like it took me 2 hours because of complications...in the end, it seems a bit loose, as in when i was gripping by the heatsink to move my mobo, it was sliding around. And trust me, I used a miniscule amount of TIM. And 'PC-Noobist' that why every place I looks is saying normal temps are between 32-38 C?

looks like a bad application of thermal paste. you must not apply more thermal paste. in fact, the less you apply, the better it is. Thermal paste conduct heat worse than copper and aluminium of which you CPU and your 212 Evo are made of. but thermal paste conduct heat much better than air ( air is an insulator). The only purpose of thermal paste is to prevent air bubble between cpu and cooler.

to prevent air bubble in your thermal paste, i recommend using the pea method. and once you started pushing your cooler in, you cannot pull it of without cleaning everything with isopropyl alcohol again.

My friend has the same cpu/cooler/mobo than you and get 20 C idle and 40C gaming

Thats normal, not every CPU is the same, also im from Australia and temperature reading is different to where you are from, i have read a few things like the situation were in now, ill let the people who know how to judge your temps from where your from take it from here on in, where are you from? alot of the time i dont find this problem so i would like to figure this out.

I have a better cooler than that and my temps are between 40-55 under load (overclocked to 4.5 GHxz)

Have a go at installing the cooler/thermal paste a bit better (take a look here http://www.youtube.com/watch?v=-hNgFNH7zhQ )

low/mid 50's is fine for that chip, just keep under 62 to be safe.

California, usually 90-105 during this time of the year.

Again, I legit only put a pea sized drop, like barely any.

Thanks for the help everyone, I'm going to install the 140s as soon as I can. In the top left corner (near my rear exhaust) I'll place one as exhaust and use the other as an intake just above my RAM to blow cool air downwards to the Heatsink, so it can absorb it. Any hot air coming out my my gpu can be blown threw the vents in the back.

By the way guys, these temps are at Stock clock speed in a relatively cool room. Later on today, I'll re-seat the Heatsink.

Also, should I consider getting another 120 mm to mount as a pull on my heat sink?
