Normal temps for I7 4770K HASWELL ?

Jarod fazmeumbroche · Dec 5, 2013

I recently built my new system with a z87-Pro and 4770K haswell cpu.

Ambient temp is at 19C and the cpu on idle is at 21C. Is that normal ?

Sounds pretty low to me and I would think it is so low that it is a bad reading.

After upgrading the BIOS version it still displays the same temps.

What gives ?

If that is the real temp then I am happy about it but I seem to be in disbeleif about such a low number.

THANKs guys!!

What cooler do you have?
Haswell do have their power-saving features which also makes it generate less heat doing idle.

that's frosty, try some other programs too like CPU-Z and HWmonitor

but if your ambient temperatures are that low (or lower) then that would still make sense, it is the winter time after all.

Sorry for being so stupid. I forgot to mention I use Thermaltake Water 2.0 Extreme.

CoreTEMP and CPU-Z both say the same temps.

I know but 3 C above ambient is pretty unreal....

If you have good air flow, low ambient, Idle, no OCs then I would say its reading right.

Run a stress test like Prim95 for 30mins and use HWMonitor to read the temps, then tell us what the max temps are on all cores.

well since you have a water cooler (even if closed loop) getting that near the ambient is still possible imo, maybe that and the luck of the draw with your CPU chip and possibly your mobo too

Doesn't all these softwares HWmonitor, coretemp, etc all use the bios temp info ?

Thank you

That's what I think also. was just surprise. Just upgraded from an i7 950 Oc'd at 4ghz and cooled with a corsair A70 idles were 30C and load at 54 tops.

I just like HWMonitor because you don't need 3 different programs telling you the same thing.
