So, some of you mght remember me from other forums, specifically OC/Forums.

Here's the planned setup to cool:

Dual 1.6ghz LV xeons at 1.6v pinmodded
ATI 9500--->9700 softmodded

so I'm thinking 2 cheap blocks, even a maze 4, and I have a Maze GPU block.

How much heat do these CPUs put out? on par with a single overclocked athlon? They run pretty cool on air. Can I get away with crappy CPU blocks?

What's the king of pumps? Still the MCP600/655?

It's been a while, but as many members here can attest, I am no noob.

The king of the Pumps is the 200 dollar Iwaki MD20RlZT or something like that but the MCP655 are the very nice pumps for the price. I would also recommand the Swiftech MCW6002 Xeon Blocks.

nah, the king of pumps is the RD20 or RD30... but they're both in the 200+ range. D5 is still good, MCP600/AQX50z is still fantastic, especially when overvolted.
and yeah to the above, i'd also reccommend MCW6002s

OFT: HOLY :banana: :banana: :banana: :banana: FCG That is freaking sweet with all the chrome.

You are right I forgot about them but then they require Extrenal power supplys making them 400 dollars so I don't think those are very reasonable.

what requires an external power supply?

and the G5s are nice, but aren't the overkill? the xeons don't get that hot, do they?

yeah, I knre about the RD20/30, but if I'm going to spend $150 more in the pursuit of a degree, I'll just build a chiller

Xeons don't get hot with the G5's, for sure. Also, they have 1.7V running through them for 3.8Ghz+ (they are the 2MB L3 cache Gallatin cores)...about 130-140W each plus my overclocked X850XT PE in the loop.

what'd you do for radiator? ~60 square inches?

FCG: why don't you have those 6 dollar a pop taiwan 5/8" flowcannons like nikhsub? tsk tsk tsk...
If i had to guess at his rad, i'd say an HE120.3 or monstercore... but thats just a guess :)

If i get MCW5000s, can I get 1/2" ID tubing into them through modification?

dont get near the 5000 series.. they are aluminum and copper mix... and that is a bad mix if you didnt already know.

greenman, what size tubing do you want to use? you prefer dc over ac? then get DDC if you want small tubing, D-5 if you want fat tubing.

there are few crappy cpu blocks these days (performance wise), no problem with maze4, seems they are cheaper than mcw6000 right now

woah, they're alumnium?!?!

Aluminum top, copper base. If you read my guide or know some chemistry you will realize the problem with that.

the 600X series do not contain any aluminum. go for that. Right now I am building a dual Xeon rig for a customer. I put dual MCW6002's in the system. Great little waterblocks. not very pretty, but very nice.

maze4 CPU? maze4 CPU is a terrible abomination carried over from waterblock designs of several years ago.

terrible abomination? yeah, compared to commercial waterblocks today, yes it is.
he's looking for two cheap blocks, and for the job he needs them for, maze4 are more than adequate. i see 35 bucks for maze4, while it is 45 bucks for mcw6002 xeon mount

MCW6002 gets my vote.

I had a pair running on my 1.6s @ 3.3ghz.

Figure about 100w a CPU at 1.6v

maze4 are still a good choice for budget / medium flow... 6000 / 6002 is defo the better choice of the 2 tho...

I think the 6002 is just better than the maze4 IMO.

maze4 might look a tad better, but its definately the worse performer.

MCW6000 is only 42.50 and actually performs better than 6002 on top of that.
MCW600x is over 5C better than maze4 at extremely low flow and around 2C better at ludicrous flowrates. I'd say it's worth the extra like 5 bucks (http://www.procooling.com/html/pro_testing.php).

I'm quite familiar, I wrote a guide on such that has been published at several websites including overclockers.com. I just did not realize teh 5000 used alu.

ah, but you must match the product ot it's application.


Storms are3 overkill, and congrats to the guy with them and all the bling, but I'd rather spend the $75 on another gig of ram. that would be way more noticeable than teh <30mhz you'll net by going from maze to storm.

remember these CPUs are largely voltage limited, not heat. I've yet to see a 1.6v xeon get over 50C while under water. right now I'm running them at stock, passive, with 2 chipset heatsinks, and seeing 45C load temps. These processors are not very power hungry.
