Cooling dual Xeons

post #1 of 13
Thread Starter 
I am currently Air cooling 2 x Xeon 18core (E5-26xx v4 series) but I want to switch over to water cooling. I have a reservoir and EK 360XT (https://www.ekwb.com/shop/ek-coolstream-rad-xt-360) radiator from my previous build but I have 2 questions.


1) is the EK 360 enough rad to cool 2 x Xeon 18core? I want to very mildly OC

2) design.. can i go Pump-> cpu -> cpu -> rad -> reservoir ->pump?


thanks in advance

They have 120 or 145W TDP, so that's 240-290W of heat, possibly over 300W. Triple rad should still be OK.

does the order of my cooling loop really matter?

can i go from Pump-> cpu -> cpu -> rad -> reservoir ->pump?

Order dosen't matter, thing that matters is which spot is best for which components.

You'd only see diffrencei with order if one components dumps out tons of heat, and the water heats up a few C and then it goes into next component heating that one up too, for exmple your xeon can dump allot of heat and your next xeon dumps same ammount of heat so its going to be hotter on the second one, to slove this, you have either two seperate water chill loops, or it goes through a radator before going into next cpu
Pump-> cpu ->rad -> cpu.

Even with a heavily overclocked fx8350 of mine, it only goes up to 2-3C in out temp diffrence of my water block, nothing siginificant here, so order shouldn't matter much

Ok good to know, I'll be anxious to try water cooling and see how much I can get out of these 12core unlocked Xeons I got my hands on smile.gif

You just said they're 18 core?
And probably not much anyway.

If you want to go hard, find out if the xeon is a soldered or non soldered IHS, if its not soldered you can delid it and you will gain much more heat trasnfer and it will allow you to increace the votlage further and oc more. but watch out though, make sure your motherboard board dosen't overheat due to too much cpu voltage

Just deliding can get your 0.1-0.2GHZ extra oc due to temp drops and or extra voltadge

Well i have two sets i want to play with 2 x 12 core, and 2 x 18 core. both are unlocked. It seems you have some info on how much headroom I should have with each?

I've never heard of an unlocked 2QPI Xeon ever. What CPUs do you have?

There are some unlocked out there, I was lucky enough to grab 4. I think I'll test them and decide which pair suits me best and then sell the other two I guess
