Then why are your Apple buddies raving about crap like how 'pretty' the Mac Pro is, and the layout of rear ports? You honestly to god think anybody with a legitimate IT job cares about that? Computers belong under the desk or in a server rack, not displayed on a desk like over proced stereo equipment. spike spiegal - Tuesday, Auglink >G5s kept up well with Intel and AMD, and were often faster - sometimes much faster - but weren't going anywhere in the foreseeable futureI don't know whether you're an AMD or Intel fanboiA computer is just a tool to get things done.It also Geekbenches well for the model at 2394 (I know it doesn't sound much, but the usual GB score for this model is 2259). The one in the "good" Mac of the two I purchased is doing a very nice job and doesn't seem to have any significant difference in cooling between the two processors. However, I can say that when these systems are well maintained they do still seem to work quite well. ordered to fit onto the Laing pump so that'll be here soon.Īs for the point about a single pump cooling twin CPUs, well that obviously isn't going to be an issue on any of our systems I'm glad to say. I'll try it out first on my older 775 based Zotac board just so I can compare performance and, if anything goes wrong, it won't be too expensive (!).Īpple didn't have a reservoir on their systems, but I'm going to definitely build one in. My idea at the moment is to use the system for a Mini-ITX implementation. Thankfully though the aluminium of the case wasn't affected, just the steel of the PSU and the cover plate. Mine was almost eaten away by the fluid and resultant rust. The case of the power supply that got leaked onto speaks volumes for that. The stuff Apple used in their loop was extremely corrosive when exposed to air.
I think the first thing after taking down one of this systems definitely needs to be draining what is left of the fluid, pulling apart what can be pulled apart and flushing. That may have been a radiator that had got clogged up as the one I have seems fine. I'm not so sure about the radiator resistance point. Thanks for all the comments so far.and the project hasn't even really begun so far. The failure mode of these pumps is the O-ring seal which costs £1.20 to replace. It's a silly little thing but finding one that has not been broken at some point is about as rare as finding a hen with teeth. I managed to extract it without breaking it and have saved it. This G5 still had the little grey rivet in place in the processor cover. Oh yes and one other thing I have NEVER seen before. Failure can also be due to burn out of the PCB (fortunately this is not the case for mine), but there is a guy on eBAy who occasionally sells new PCBs that he makes from new surface mount components. If testing dry then only run for a second as the pump uses the coolant to lubricate itself. To test, connect 1 to ground and 2 and 4 to 12 v. The connections are as follows: 1 = ground, 2 = V mot (variable), 3 = Tach output, 4 = 12v motor. When looking at the connector to the pump end on, the pins are like this: I am replacing the seals on mine and going to see if it does the business.įrom testing, the usual black Apple wiring to the pump plug is a six pin connector with 2 blanks. The pump is labelled Delphi, but in reality it is a Laing pump which is the standard for most proper water cooling projects and is fairly expensive ( the retail version is about £60). It has a brilliant little 140 mm aluminium radiator that looks bullet proof (pic attached). The working one I re-furbished, but on the spares machine I decided that the water cooler is too good to throw away.
The thing is though having only seen air cooled Mac.s I was really interested by the lovely looking water cooler in both machines.
The other though is dreadful.a nice case (well, that's what I bought them for really) but a cooling system malfunction took out the power supply big style. From these two I actually got one working really well and have overhauled for sale. Recently I got hold of two defective G5 2.7GHZ dual machines. This is going to be a slow burning thread, so patience required (!), but I thought it might be of interest and worth a post or two. Building a CustoMac Hackintosh: Buyer's Guide
