Thank you for sharing the pic. I must ask, what is the pump and what is the CPU waterblock you are using ?

Hi again.

During overclocking, i was not satisfied with the CPU temperature that climbed up to 68 C under load with p95 at 5GHz. Analyzing the topography of the case components i noticed that Scythe 140 mm 1700 rpm fan does not cover the entire surface of the VRM water block region on the back of the motherboard. So, I decided to replace the 140 mm fan with 120 mm 1900 rpm Scythe Slip Stream fan, and i literally pushed another Scythe 120 mm 2000 rpm slim fan in the area between 1900 rpm 120 mm fan and the upper edge on side panel of the case ( enclosed picture ).



With both fans i managed to cover the CPU area and VRM water block area at the back of the motherboard and decided to try test with p95. I ran p95 custom torture test at range from 8-40 FFT size (maximum heat ) 15 min. each session for 2 hours, with these settings in bios: BCLK 100, ratio 50, vcore 1.52V offset, LLC medium, VCCSA LLC regular, VCCSA voltage 1.1V, DRAM 1600 , 1.6V.






Ambient temperature was 27.5 - 28 C. During maximum p95 load vcore value was 1.47-1.48 V. What suprised me most was CPU temperature and the fact that only one core was above 80C, accurately 83C. CPU temperature maximized at 56 C for about 5-10 second, with the most frequent value at 53C.















So, in my case, actively air-cooled rear CPU and VRM region, in addition to water cooling resulted in a significant decrease in CPU temperature ( 12C ) during intensive load with p95 test at 5 GHz frequency. I hope that this information will be of use to someone.

Cheers.

I have the same finding. Active cooling the back side of CPU helps a lot, especially for the motherboards which has VRM chips located on the back.
Motherboard consists of a large portion of copper. Hot spot under VRM increases CPU temperature. So cooling the area around the CPU always help.

I have 3 fan's on radiator and all 3 of them are controlled by PMW in BIOS (they are connected to CPU header on mobo). I got the same results like you got for CPU temperatures but it caused that fan control reduces speed of fans to 600 RPM instead of 2000. Consequence of this was that core temps was for 10 and more degrees higher than normal for the same load. Also respond for the temperature change was to slow .

Using fan's at maximum speed all the way it is not an option for 24/7 home use of computer. Should I remain you that thermal monitoring is not only dedicated to fan speed. It is quite possible that based of this CPU temperature processor will allow additional load (current) which can burn/degrade your CPU.

try running LinX next. On my old config, i could run hours and hours of p95, but then I ran LinX and it crashed in about 5 minutes.

How were you running Prim95? Small FFT? Blend? Be more specific please.

As of yet i havent found a time where ive been Prime95 Blend using 85% Ram stable and LinX unstable.

I still don't understand the connection of fan speed reducing and overclocking in your case. If cpu or core temps are rising why would fan controler reduce rpm? Anyway, i have 2 independent 12 chanell Scythe fan controllers. Only 2 fans are connected to the motherboard. Also, when CPU reach maximum allowed temperature ( about 91C i think ) it will shut down. It's not so easy to burn cpu. I tried. So the main problem here is the risk of the cpu degradation. It's the risk you have to take into consideration when overclock.
