As 990fx Extreme 9 CPUTIN High Temp [Solved]

Nice system. See my Sig below.


Two things.

1. A must. Have you pulled the clear protective covering off the the three tin shields on the motherboard ?

2. Another must, matter of fact it is required when watercooling. Put an aux fan blowing over the components surrounding the cpu socket. With the better part blowing over the VRMs to the left of the socket, under the tin that has 990FX printed on it.

The manual states that for the FX 8xxx and 9xxx you need a CPU cooler that blows down onto the VRMs and surrounding components. If you are using water cooling or a tower cooler then an auxiliary fan is needed for that purpose. This is due to the amount of voltage the higher end FX CPUs draw and is a well known issue regardless of board or manufacturer.

Exactly.

Along with the FX-9590 you purchased, inside the packaging you should have also found the below paper from AMD stating so also. See #3 on pg1

www.amd.com/Documents/FX-9000-Installation-Guide.pdf

is written in the above link, pg1 wrote: 3. Chassis exhaust fan mounted near the motherboard VRM components with at least  35CFM of air flow capacity.

Which ASRock states, rather weakly I may add, on the below page at the top also. Note the red asterisk as that's what Xaltar is referring.

AMD and ASRock worked hand in hand in designing the 990FX Extreme9. They also realized that although the 9590 would be used with a normal HS/F, the highly preferred means would be as watercooled, which in no way the the pump circulate air over the VRM section.



I sux at describing this yet I hope I got my thoughts across to you concerning, regardless.

I have bought a laser thermometer with a case fan 75CFM pushing air to the VRM disipator and check it (photos): https://drive.google.com/drive/folders/0BwyzeSh2fR-oMWZtSDBNdFNKY0U?usp=sharing

Yes,  Now i have OC to 5,1GHz 38ºC 32 Margin termic  22 Ambient and 73ºC on CPUTIN Is is very rare because this temp is behind motherboard behind of the VRM but in the 990FX Disipator NB the temp is 42ºC MAX with the fan.. before 71º and crash my pc no reply..now I neither understand anything :S Now my PC works but ...why? if the temp also is very high?
