Hey, so I just about finished up my first ever PC build yesterday and am not sure whether or not I did something wrong or if I should be worried about the temperature readings that I am getting.

I have a 3570k with Hyper 212 +
ASRock z77 Extreme 4
8gb Crucial ballistix sport 1600mhz
MSI GTX 760 TF/OC
OCZ ZT 750
120gb Samsung Pro SSD
Corsair Carbide 300r

I ran Prime95 for 2 hours on the "Blend" setting and was getting

Core0- 58 -59
Core1- 61-63
Core2- 64-67
Core3- 60-63
Package-64-66

At idle I am getting around

Core0- 31
Core1- 25
Core2- 36
Core3-32
Package-35

Now like I said, this is my first time building a PC, ever and I am curious as to if I did something wrong as in applying not enough or too much thermal paste? Or not applying it properly? I assured that my cooler was tightened all the way down, and I am running 2 intake fans, 1 side intake fan, 1 exhaust fan, and of course 1 fan on the cooler. I do plan on overclocking in the future, nothing too extreme and just want to make sure that my temps are okay for now before I proceed any further.

Thank you for the input and I apologize if I gave any wrong information or not enough. I am still fairly new at this and am learning as I go.

I think with those temps and the evo you might be able to go up a little. Ivy bridge runs hot man but you could go up a little then check the temps. I use HWmonitor and it works good. Give it a try you have a little room to move

Yeah I figured that was a bit high. I am just not sure what I should do about it? I used the thermal paste that came from cooler master with the cooler and wonder if maybe that might be part of the problem?

Actually those temps look pretty good. I have a 3770k and I cool it with a h100 corsair liquid cooler. I overclocked mine to 4.6ghz and see temps around 70c on full load. So those temps under prime 95 load with a 212 seem fine.

Would it be safe to say that I have room to overclock than? I wasn't planning on doing anything extreme, but would like to have the option using this cooler in the future for a bit of a performance boost if I need to.

Thank you for the input. Ill play with it a little more in the future. As long as my temps arent insanely out of the ordinary I am not too worried for now.

If those temps are at stock speeds, they are a little high. I'd expect those to be at a 4.2ghz+ overclock. I'd play it safe, and double check how well you've attached the Hyper 212 Evo. Also, what was your ambient temperature like?

That might be my best solution, I will go ahead and pick up some new paste on Monday and reapply paste and everything else. Any recommendations on thermal paste? And the safest way to remove the old?

Points:
1) Those temps appear very NORMAL for that cooler.

2) My i7-3770K (at 4.2GHz) was stressed with P95 using the "max heat" setting for all eight threads. I used a better cooler (Noctua NH-D14) and peaked at about 71degC. I would expect maybe 2degC difference between our CPU's due to the hyperthreading (mine is hotter). Your temperatures will be DIFFERENT from someone else, even with the same CPU. Reasons:
- ambient room temperature
- CPU cooler
- case fans (don't forget the INTAKE FAN or FANS at the front)
- Graphics card and other hardware
- CPU/Case Fan profiles (i.e. running at 100% or automatic on a RAMP)

3) Overclocking:
I don't recommend overclocking beyond 4.2GHz. I managed to hit 4.2GHz using the Asus automatic overtune feature so I didn't have to disable any POWER SAVINGS FEATURES.

However, when I attempted a modest 4.4GHz I had to make several changes to prevent crashing. These changes causes the temperature to shoot up to 88degC. This may be DIFFERENT for you though. I decided a stable 4.2GHz at a much lower temperature was ideal.

4) Overclocking beyond 4.2GHz is unlikely to make much real-world difference playing GAMES. I tested games (FRAPS) and ran some benchmarks at 4.2GHz and 3.7GHz (500MHz apart in Turbo) and the difference was either minor or non-existent (likely since I'm often GPU-bottlenecked despite my GTX680).

5) MEMORY:
It's easy to screw up your memory settings. I generally prefer "XMP" for Intel which sets things automatically to the correct setting. Regardless if you use XMP or manually change memory don't forget when your changing CPU settings that your memory might change (i.e. 1333MHz instead of 1866MHz).

Always run MEMTEST (or similar) if Memory has been changed and Prime95 (or similar) when you change the CPU settings.

Summary:
- temps are normal
- consider overclocking to about 4.2GHz (especially if you can maintain most power savings features)
- If overclocking beyond 4.4GHz is important I suggest a much better cooler.
- double-check your MEMORY settings are correct.

Honestly it seemed like my fan speed stayed the same. HWMonitor showed my fan CPU fan speed at 2000 the entire time.

Thanks. Definitely sets me at ease to know the temps are not that out of the ordinary. I don't really plan on overclocking past a mild clock as I don't think I need it because I only use my PC for gaming and school work such as Microsoft Word and internet surfing. How am I able to check my memory settings? I know that in the BIOS I had 2 profiles to choose from, either 1.35v 1600mhz or 1.5v 1600mhz or an automatic setting which I left it as.

Travisbarba,
1) I recommend the automatic setting for RAM. For Intel, if you click "XMP" it should automatically apply the default, optimal settings for BOTH your RAM and your CPU.

When you start your PC, the BIOS recognizes the RAM (unless it's too new). It has the proper frequency and other timings for your memory. (When a PC is unstable, sometimes it is because the timings or frequency for RAM are incorrect because the BIOS doesn't "know" the proper settings. This is why a BIOS update sometimes solves the problem. A profile for the RAM might be included in the new update.)

2) Mild overclock:
My motherboard had a setting that automatically created a mild overclock. Yours probably does too. In my case, I clicked it and the PC rebooted as the BIOS applied the new settings and tested it. When I re-entered the BIOS it was at 4.1GHz (but my RAM was at 1600MHz though optimal is 2133MHz).

You may have to experiment slightly with a mild overclock to ensure your memory is proper. You may even have to manually make the settings.

3) You likely also have WINDOWS SOFTWARE that can overclock your CPU with a single click and reboot. Just double-check the RAM frequency and run the diagnostics.

My advice in your case is:
a) overclock CPU to 4.2GHz (without changing any other CPU power settings or voltage if possible). Use BIOS or Windows software.
b) use AUTO for memory if possible, manual if necessary
c) VERIFY both RAM and CPU settings one last time then TEST both with Memtest/P95.

Other:
Your CPU temperature won't be as high even when gaming as a P95 stress test.

Summary:
Recommend mild CPU overclock to 4.2GHz, ensuring other settings correct.

I will definitely keep this in mind when I get to that stage of overclocking. Thank you for the heads up! I appreciate everyones help and replies!

Enjoy that rig man. Looks pretty sweet. I have a gtx 680. Everything is in a nzxt switch 810 I just built a couple months ago and I don't even touch my consoles anymore. Steam sales FTW!!! Lol enjoy

Thanks brotha! I am looking forward into getting into the PC world and steering away from console. I finally had the means and reasons to justify making the switch. Im excited.

I went ahead and checked my BIOS and it does in fact have a turbo feature but for some reason clocked my CPU at 4.7ghz. Not sure why, but I will go ahead and mess with a 3rd party in windows program once I get everything up and running.

If I do happen to go ahead and apply new thermal paste can you recommend any useful tips? I read the best way to get it off is to use a tissue and isopropyl alcohol and rub it off until clean? Thanks again man.

WARNING!!
4.7GHz is way too high. You'll CRASH your PC at that setting with your cooler. You MAY get lucky but I doubt it.

i5-3570K Overclocking and TURBO settings:
- 3.9GHz is default
- 4.2GHz is a MODEST overclock which probably can maintain power savings features
- 4.4GHz requires TWEAKING of certain settings and your cooler may be borderline to keep it cool under load
- 4.5GHz to 4.6GHz requires a better cooler
- 4.7GHz+ generally UNSTABLE regardless of setup for the average person though some have been successful with good coolers

THERMAL PASTE:
There's a lot of good info out there.
Paste: http://www.maximumpc.com/article/features/geek_tested_17_thermal_pastes_face?page=0,1

That may not be up to date, but anything recommended is good stuff.

You can GOOGLE for the proper way to spread and how much but it's ROUGHLY like this:
1) squirt the size of a small pea (many apply too much which actually INSULATES instead of conducting)
2) Spread with a credit card (the middle square 1" is the important part)

As long as it's fairly even but not too thick you're good. Figure out the best way before lining up the CPU heatsink as you can smear your heatsink material all around.

CLEANING:
- isopropyl alcohol
- use a rag which doesn't leave THREADS
- verify it's clean with no threads (and don't TOUCH after with your fingers, just the credit card and paste)

OTHER:
I remove the motherboard completely and sit on an anti-static bag or other suitable material that is then on top of something with a little GIVE so I don't damage the motherboard when working with the heatsink.
