Gigabyte GA-X38-DQ6 + Thermalright

[Jules]

Hi guys,.. first time here

- I've seen pictures of the Thermalright Ultra 120 Extreme with the fins mounted vertically instead of horizontally so the air is sucked through the fins by the 120 mm fan of the PSU.
Would this result in sufficient cooling if none or only some mild overclocking is needed?

- If a Scythe S-Flex SFF21F 120mm fan (3 pin connector) is connected to the 4 pin connector of the MB will the fan speed be controlled by the MB when CPU temperatures vary?

The aim is to cool the CPU without the fan for normal use.
When the CPU gets stressed the fan has to jump in.

I think this sentence must be confusing, sorry for the poor English, I'm Dutch speaking

I'll try to explain it better

- Normally this heat sink is placed with the concave surface and fan facing the RAM slots.
Would it be a good idea to turn the unit over 90° clockwise?
(The opposite long side of the heatsink is then directly under the 120mm fan of the PSU)

Welcome to the forums

Yes, if you put a 3 Pin fan connector on a 4 pin socket, it will still control the speed.

Providing that the heatsink will fit on your board that way, I can't see any problem fitting it like that.

The only problem you may have, is that the PSU gets warmer, and spins up a bit faster than normal. Just try it and see

Thanks Clunk,

I'm still in the phase of gathering information needed for building a new rig, it has been seven years since I've built the former one (A7V133) and things have changed a lot, if you ask me.

So, if you guys will allow it, I'll come back here when some fumes have to be swept out of my poor brain.

It will run the fan , but not control the speed, 3-Pin and 4-Pin Fan Connectors

when using a 3-pin power connector with a 4-pin fan header, the fan will always be on; there is no fan control.

You might try plugging the fan on a 3pin header on the mobo & try to contriol it from there. There are some 4 pin pwm fans you can get. Arctic Cooling 120mm PWM fan #AF12025PWM Cooling PST (PWM Sharing Technology)

the Thermalright Ultra 120 Extreme should fit fine, mounted either way.

Oops, I stand corrected

That is exactly what I was looking for

- 2X Arctic fan PWM 80 (Front mounted air intake for cooling 3 HD's)
- 1X Arctic fan PWM 120 (CPU cooling)
- 1X Arctic fan PWM 120 (Rear mounted, exhaust casing)

All of them bios controlled through the 4 pin CPU cooler socket on the GA-X38-DQ6.

Hang on there is only 1x4 pin fan header on the mobo for the cpu fan header. The others are normal 3pin headers.

That 4 pin fan header can be shared ( look at the documentation of the fan)

Oh right not thought of that.
