Depends on the budget. Is that within the budget? http://pcpartpicker.com/product/xz4gXL/asus-motherboard-sabertooth990fxr20

 

It's basically the top motherboard for that chipset.

Yes it is. Thank you

Then it is a much better buy, people have been setting FX overclocking records on those boards. You're welcome, I myself had an FX-8350 based AMD system and I know quite a bit about those.

I would like to point out that @BurneyThePleb has exactly zero fucks partnered with no fear

This build will work even if it kills him

  The FX9590 has a TDP of 220w, I doubt a single 120mm rad will be able to handle that.

An H80 or a Nepton XL will do. 140mm rads will do as well.

The "220W TDP" scares many people, but they expect unrealistically high temps, ignoring the fact everyone is OCing the FX-8xxx to 4.5 and beyond, not precisely with liquid nitrogen. FX-9xxx CPUs don't need anything beyond what an OCed FX-8xxx would need.

 

The real concern are the motherboard's VRMs, because the vcore is ridiculously high out of the box in the FX-9xxx series, much higher than what it takes to OC the 8xxx to the same speeds. I have an FX-9370 with 1.54v vcore out of the box. The H80 handled it fine, but the VRMs were frying. That's why the motherboard is more important than the cooler. But I would undervolt the 9590 anyway, no point in using more vcore than strictly necessary. The 9370 went to 1.38v easily.

 

The Gigabyte UD5 will work with the 220W CPUs, so will the UD7. The Sabertooth is always a good choice as well. ASRock has two boards that will handle them right, the 990 Extreme6 and the 990 Extreme9. The Extreme9 is the best AM3+ board when it comes to handling power hungry chips, but the Sabertooth won't do worse.

Thank you for explaining the "science" behind FX9xxx. Also would a 120mm fan pointed at the motherboard help at least somewhat ?

A 120mm fan say resting on the gpu backplate couldn't do anything but help lower temps, but doesn't look the nicest when you have a windowed side panel. A small fan behind the board helps quite a bit, I've got an 80x80x15mm resting on the cpu backplate with double sided 3m tape, and stays hidden under the side panel with no window.

not like resting on the backplate. More like... Taped to the side on an angle...

Yes. I have a 92mm mounted over the VRM heatsink of an ASRock 970 performance (not recommendable for these CPUs), and it reduced the VRM temps by a more than 10 degrees. Similar story with a 60mm fan (taken from the stock cooler) placed on the VRM heatsink of a Sabertooth board with an OCed 8370e.

I'd go with whatever can blow some air directly on the relevant area while not blocking too much your case's airflow.

You can find my "fan mounted on a slot cover mounted on a fan" solution in the following post

i will figure something out. by the way, what PSU do you have ?
