Question about Haswell temps in custom loop

[Milena]

I build a custom wc loop for my FT-02 (first time ever, pics will follow soon).

Magicool 540mm rad, Laing D5 Pump in a double 5.25" XSPC bay Reservoir, Aquacomputer Cuplex Kryos HF CPU Heatsink and 13/10mm tubes. The GPU Heatsink is the EVGA Titan HC one.

The loop is working nice so far but I still see temps up to 76°C during long time Prime95 large FFT runs. The GPU never goes above 35°C under max load. I used CLU as thermal paste for the CPU.

In comparsion, I got up to 88°C with a Corsair H80i during large FFT's before.

Is 76°C peak normal for a 4770k in a custom loop? The CPU is at 1.200v now for 4.4Ghz.

Thanks and kind regards

Your temps seem fine for those clocks and voltage.


Look into delidding if you want to improve temps.

But he's using a really good custom water loop, i think his temps should be a lot lower, even thought it's for the 4770K.
