Hello people, I am here thanks to bullydog who is the pusher of my start in the art water cooling. And yes, I have just inherited his beautiful Nickel plated HK 3.0 and have been trying to pick his brains ever since...
OK, the issue is that my 2500K (at 4.5GHz ~1.280V load) idles very nicely with EIST/C1E around 28-31C all cores (CPU Digital Thermal Sensors as read by hwinfo64) but load temps (which is more impt) seems to have improved only a little over the Antec Kuhler 620 I was using - readings of 60-65C now vs 65-70C previously.
Perhaps I am expecting too much from water but the funny thing is that to my finger everything feels cold - the HK block feels cold, the rad feels cold so somehow the heat does not seem to be transferring well from the chip to the block or... maybe the DTS readings are just too far off.
So I double checked with my cheapo IR heat gun on the test rig when running LinX. While hwinfo64 reported temps of 59-65C CPU DTS on the cores, below is what the IR gun reported
1. Side (bottom half) of HK block 35C
2. Top of HK block 32C
3. Radiator Inlet from block 30C
4. Swiftech Micro-res 30C
Seems my finger is reporting correctly since the IR gun reports everything as being below human body temperature.
So far, I have remounted both CPU and block, re-oriented the block, re-applied TIM repeated times, also tried out on another mobo but the load temps remained roughly the same. lol
Would appreciate your thoughts and thanks in advance.
