Are my i5 3570k overclock temps good?

Today I got my Coolermaster Hyper 212 evo heatsink and attached 2 Coolermaster Sickleflow green led fans.

PC Specs.
i5 3570k
sabertooth z77
asus gtx 770 directcu II
16gb corsair 1600mhz ram
corsair cx750m psu
830 256gb ssd
7200 rpm 1tb wd blue hdd

Also I am doing a prime95 torture test.

So... are my temps good?

if it stays at those temps after an hour or so thats really good, it looks like you had only been testing for 7-8 minutes at this point, its generally better to let it run for a while so you get a good judge of your max temp over time and stability of the system

15:38 to 15:46, 8 minutes does not give you the maximum temps.

My room temp is about 23° I just upgraded to the hyper 212 evo today and also I am using MX-2 thermal compound used in the x method.

I'm going to go out later and will leave it running for about 5 hours, when i get back i will update the screenshot.

Best solution

Temps look OK sofar (I'd probably NOT say Great), However:
NOTE: Great would be upto 20C > than ambient ie mid to low 50s
1) Do need to run a little longer. I find that Prime95 (blend mode) will reach close to max within 10->15 min.
2) Prime 95 will heat the cores up more than the vast majority of Games, so gaming should result in lower temps.
3) You have a "K" CPU, so I'm guessing you are planning on OCing. This will increase temps and depending on if you have to increase Vcore it could result in an increase as much as 10->15 C.
4) You should run Prime95 for at least 4 Hours to Check Stability, espeacially with Overclocking and that will also show what max temps would be. Need to watch closely for first 15 Min. If not above 70 C should be good but if hitting higher then need to monitor untill you see it stablize.
Your CPU is good upto 80->85C for a short period - Throttling starts at around 100C and if the decrease in speed does not stabize temps then shutdown happens around 125C.

Point of reference, I have a i5-2500K OCed to 4.2 GHz (good upto 4.8, but just not that big of difference from 4.2->4.8). The i-2500K does run cooler than SB CPU so have to take that into account, But my temps:
58->62 C, prime 95 after 30 min. Have the Zalman 9900Max HSF (Somewhat expensive but I like it).

My prefered method for HSFs that have "valley" along the heat pipes on the Base is to use a credit card and completely fill the valleys (none on the "flat surface"), then use the "x", or Place a small amount on the Top of the CPU and spead VERY thin using my finger (latex glove).
