Liquid Cooled Systems

Unread postby QuicksilverG4 » Sun Jul 08, 2012 3:38 pm

Being a Mac person I'm well aware of the liquid cooled G5 (especially the quad :)) but I've never owned one. Though a few months ago I was playing around with an HP workstation and was surprised to find HP made a liquid cooling system that could be installed in place of the standard heatsinks and fans and it takes about 5 mins to install.

That got me wondering about other systems that came with stock liquid cooling. I'm thinking more desktop/servers than huge supercomputers with liquid-cooled doors :) but post anything that you think is interesting.


Apple Power Macintosh G5 Info from everymac.com.

2x 2.5 GHz G5 (2004)
2x 2.7 GHz G5 (Early 2005)
2x 2.5 GHz dual-core (Late 2005)


HP XW9400 - HP Datasheet PDF

Dual Opteron workstation based on a slightly modified Tyan S2915 motherboard. Liquid cooling was an option on higher spec'ed models and since the water blocks, pump, and radiator are all a single unit, it can be added to any system. With a BIOS update 2.8 GHz six-core Istanbul Opterons are supported.

I had the HP maxed out with twelve 2.8 GHz cores and the liquid cooling system but downgraded it to the original dual-core processors when I bought my Mac Pro and put the standard heatsinks back in. Here's some shots of the cooling system. The radiator replaces a large rear case fan and the rest of the unit sits over the processors. I never did any serious testing of temp control and noise though the system was quiet and the CPU temps around 55-65 C under 100% load for hours.

It's not quite what you asked about, but the old mineral oil trick is still out there. http://www.pugetsystems.com/submerged.php

I used to have one of those HPs but not with the liquid cooling. Good solid machine, at least considering it's a HP PC that runs windows, I never had a problem with it.

You can also roll-your-own, I have a friend that did this, with a waterblock on the CPU and two graphic cards; and a bucket, aquarium pump, radiator, and some fans... they sell the stuff at best-buy.

HP also offered liquid cooling on their dual-Xeon Z800 workstation. There's a PDF available from HP marketing about it.

I seem to remember my old shuttle desktop system came with a small liquid cooling system.

Here's a bit of trivia.

Code: Select all

Which SGI(s) did come with a CPU fan?


Code: Select all

Which SGI(s) are "overclockable" (without changing cpu).


And by SGI, I mean mips of course; the rest doesn't exist.

The 100MHz IP17 (Crimson) of course :D The 1GHz IP53 (duct with blower assembly) and 4D/35 (mysterious & rather useless little fan hovering roughly above the CPU) are corner cases.

I'll leave it to someone else to mention the R10K O2 and Indigo2 ;)
Now this is a deep dark secret, so everybody keep it quiet :)

That would be the Origin and Origin-derived architectures (IP27,29,31,35 (and derivatives))

CPU speed is set via the "flash" command. Note that you may not be able to successfully overclock it, depending on the CPU.

Some IP12s came with 40MHz R3ks in the socket, so you could go up within-spec by changing the oscillator.

As far as liquid cooling, the "boiling Flourinert" system always seemed like it would be the coolest. In a clear case, naturally.
Damn the torpedoes, full speed ahead!

This is certainly true for the (36MHz) 4D/35. There's no such thing as a 36MHz R3000 CPU. Then again, the 4D/35 is well known as 'thermally challenged', overclocking one would be pretty silly.

I've owned a 4D/35 with a peltier cooler on the CPU. This too baffled me: while a peltier cooler cools the CPU (somewhat), it also introduced yet more heat in the E-module. Didn't seem like a wise thing to me...

R10k I2:s have a little one embedded in the heatsink block IIRC.
