AMD Opteron 8439SE watercooling

Tom_05 · Jun 4, 2015

I have been running 4 AMD Opteron 8439SE on a SuperMicro H8QME-2 board for the past year and the case (SuperMicro SC-748 w 1400W Platinum) can barely keep up with the cooling. It is REALLY loud, like a vacuum cleaner and the thermal alert buzzer lights up every time I do anything other than look a the desktop.

I need to use the machine for a minecraft server and terminal services. On terminal services as soon as 2 users log on the buzzer goes off indicating the temps are over 70C.

I have 4 heatsinks (with 4500RPM fans) currently and the supermicro SC-748's 3 Ultra-Flo exhaust fans at 7500 RPM and some premium 8500RPM midway fans. I am looking for a way to get the temperatures under control lets say running around 40C-50C and maybe 60C when I have maxed them all out during rendering 3D
What do you suggest?

I suggest getting a pre-made CPU watercooling kit like one of these- They are cheap and easy to install with no maintenance. - http://www.msy.com.au/saonline/pc-accessories/15019-coolermaster-seidon-120v-plus-rls-12p-20pb-universal-cpu-water-cooler-with-blue-jetflo-fan.html

Most liekly you need, clean CPU coolers and, put fresh thermal paste on CPU, is no way that standard cooler cannot keep up with cooling.
Any way exhaust fan is ok add intake fan to.

Hello,

Your best solution is to do a custom water cooling system; because of the layout of the case, the radiator will be mounted outside the case: http://www.swiftech.com/H20-220ultimaHDliquidcoolingkit.aspx

Or, if you can find a way to fit a pair of these at the back of the case:
http://www.swiftech.com/H140-X.aspx (they have 140-mm radiators though)

Why a pair? Because they are expandable, so a single kit will cool two CPUs, you just need to buy two more waterblocks, some tubing and follow the instructions about bleeding the system.

It will be some work involved, as the plastic shroud covering the CPUs should remain in place, providing airflow to the CPU VRMs.

What is the point of paying hundreds of $$$ and risking it, when you van pay about $75 and ytou can get a risk free water cooling solution? There is no point in getting a custom water loop.

Very simple: because he has 4 (four) CPUs

celtic_warrior99 · Jun 4, 2015

Ash. OK I understand. I agree than. Go for custom water loop.

All righty, quad Opterons

Your case is fairly straightforward. The H8QME uses the standard 3.5" heatsink mounting pitch that AMD desktop processors use and you have a 4U chassis. The only issue is that the sockets for CPU0 and CPU1 are squished right tight next to each other, which is unfortunately a Supermicro tradition on AMD quad boards. (My H8QGL is the same.) I would go get yourself four of the plastic heatsink retention brackets for Socket 754 or 939 so you can use regular AMD desktop clamp-on heatsinks such as for Socket AM2 or AM3 instead of screw-in server heatsinks. A 120 mm sink will fit in your case but will interfere with the adjoining CPU socket for CPU0 and CPU1 unless you can turn it sideways, which some sinks allow. A 92 mm sink should *just* fit in the "normal" orientation.

Supermicro sells a pair of 80 mm fan heatsinks (SNK-P0020AP4) that you may have on your board already. I have roughly similar sinks on my dual 80 watt LGA771 Xeon X5260 server (SNK-P0034AP4) and they would probably be a little outclassed with 140 watt CPUs like your 8439SEs. I run a pair of 92 mm SNK-P0050AP4s and I had to nibble off about 1/4 inch off of the width of one of the heatsinks to get them to fit side by side as G34 heatsinks cannot be rotated. That size of a heatsink cools my 140 watt 6287SEs just fine though. So, I'd look for a 92 mm AM2/AM3 heatsink that you can rotate and you should be more than good.

Any way to water cool it to be quiet or no? Do compatible watercooling adapters exist for those AMDs or no?

Yes, there are.

Socket 940, Socket C32, and nearly all socket F boards use the standard 3.5" heatsink pitch that all Athlon 64 and later desktop boards use. Get a Socket 754 or 939 two-bolt retention bracket and simply attach it to the board, and use your favorite 754/939/AM2/AM2+/AM3/AM3+/FM1/FM2/FM2+ clamp-on water block.

G34 and a very small number of TYAN Socket F boards use the unusual 4.1" heatsink pitck. However, there are still G34 water blocks out there. EK makes a version of the Supremacy that fits the G34 socket, and Koolance offers an adapter for the CPU-360/370/380 for G34. There may be more blocks out there as well.

Clamp on water blocks don't exist in my country, which screw on ones are compatible? I have the brackets and the current fans are clamp on. I looked on the internet and could not find any clamp on water blocks? Do they exist anywhere?
