i5 Stress Testing Temps

[AmrAlaa15]

I've recently built my first pc. The cpu of the build is intel i5 4690k and I am using corsair's H105 cooling unit in my h440 to cool the cpu. 
When I used prime 95 tests to check my temps, it was pretty high
at stock speed the cores were at 62 degrees I believe
I did little overclocking to 4.2 GHZ at 1.150v , the temps of cores in Core-Temp were 72-78 degrees celsius 
I now installed Aida 64 and at 4.2 ghz the temps are amazing 
The cpu average temp was 42 and the average temps of the cores were 49-50
So I am alittle bit confused which is more accurate in stress testing the i5 4690k
I even overclocked it now to 4.5 ghz at 1.2v and the temps of the cpu is 48 at average and the cores are around 57 degrees average 
there is no crashing or what so ever.
I've read online that prime 95 overheats the Haswell cpus but I need confirmation on that one.

Don't use Prime95 on Haswell chips.  When stress testing an overclock, anything 88c and below is fine as you'll never reach those temps while gaming.

i'd like to add that 7zip's built in benchmark is a great test for real-world scenarios, in case you want to see what the figures will be when doing your everyday stuff.

^That^ 

AND, 88c is really too high. I don't even let my laptop get that hot when gaming. 

I try to keep the CPU under 75c and the same for the GPU.

I'm not sure why AIDA64 was so much lower, but even your Prime95 temperatures were okay. Prime95 is a torture test and will show you much higher temperatures than you're ever likely to find in real-world use. I wouldn't be alarmed to see up to ~80°C in Prime95. If it was stable, I'd say you're in good shape.

75c when overclocked and stress tested on a desktop CPU is nothing.  Even stock clocks will be able to reach those temps if you push it hard enough.  Below 90 is fine.

Seconded.. although myself I aim for under 85*c, but up to 80*c is nothing....for an OCd CPU.

I used 85°C as my cut off. I used occt to stress test, aida works well too, but needs longer runs I think
