like the 5th time ive remounted my h100i to my 4790k because everyone else seems to be getting better temps than me but im still not having luck.

at first i had 28 degrees at idle and about 58 degrees during load using p95(26.6) at stock clocks (4.0-4.4ghz) which are normal temps i think?

i then tested some overclocking, got a few bsod's. and now reverted it to stock clock again and im getting about 62-68 degrees in p95 with 1.2v. my core 3 also consistently runs 10% cooler than the rest of the cores idk if thats normal or not. so bassicly my temps have increased by like 20% within 20 mins.

im using corsair sp120 fans that spin at 1.1k rpm during load, i dont know my ambient temp sorry.
 
Solution
Tough to say why your temperatures changed, but 68c is still an amazing temperature for that CPU at that clockspeed.

You're right that at stock settings you should be closer to 55C not 65C, which suggests either you should reseat the water block, redo the thermal paste, or that your fans are simply not as powerful as others / there's some air flow explanation.

However I wanted to chastise you a little about using percent increases in temperature. You can do that with Kelvin, but not C. You can do that with differences, but not absolutes. For example, 60C is not 20% hotter than 50C. It's 10C hotter. It's actually only 3% hotter -- 333K vs 323K. If you compare to a 28C idle, then you were getting a 30C load increase (30K increase) but now you're getting a 40C load increase (40K increase) -- this is a 33% increase.

im pretty sure the waterblock positioning is fine now. Whats weird is the fact that about an hour ago when i reseated my waterblock, i was getting 55-60 degrees in my first p95 benchmark and 28 degrees in idle. after trying to overclock to 4.7ghz and failing, i reset everything to what they were and now im getting much higher temps. maybe this is because of the thermal paste spreading? idk.
