with stock setting my cpu is 19-22C idle and max of around 55C full load prime95.
OC to 4.3GHz it is stable at 1.225V and 20-23C idle but underload it hits 89C max but averages around 55-60C. i feel this is too hot for only 1.225V and if I lower the voltage to 1.22V the pc wont boot, so lowering voltage is not an option, and when i lowered the clock to 4.2GHz it still hits 89C and wont boot with 1.22V
need some help.

using gigabyte z-97mx gaming 5 mbo and corsair vengeance 1866mhz 2 x 8gb

thank you

Haswell gets really hot when running Prime95. It's generally not suggested to use it when stress testing Haswell. Use a more realistic stress test such as the one I posted. unlike prime it uses real world programs which represent real usage.

The option to move forward in your overclocing adventurer with that 4770K is to delid and replace the stock tim with something of higher quality, preferrably CLU. I've gotten my 4770K prime95 (the hot one) 24hr stable at 4.5GHz with 1.27v at under 80C on a Swiftech H220. My typical usage was at 4.3GHz and 1.185v and under 70C in the same test.

Whether it's worth delidding, that's up to you to decide. Average OC on 4770K is 4.5GHz at 1.3v based on data in the owner's club.

i mangaged to get 4.7ghz on my 3770k with temps under 70 during prime95 at 1.25V but thats with a custon open loop and any oc past 4.7 is just unstable no matter what the voltage. i was just thinking that an h100i would be better than 89C with only 1.225V and 4.3ghz
