I am looking at water cooling for my current build (specs on the left) I've been looking about, and can see there aren't many people with a Cosmos, and even less have used it for water cooling (with some having ravaged the case to add in water cooling, which I do not want to do, at all). Right now, my plan is: A radiator on the top, where the two top fans are (plenty of space there, between the top of the case and the top edge of the motherboard). MaximumPC fitted a 360 radiator on their Dream Machine 2007, so I'm thinking that, a 240 would work just fine up there (and further, I have been in contact with a guy that's used a 360 on the rear, and a 240 inside at the top, which all fitted just fine) 1/2" tubes all around, is what I'm thinking, so, higher flow, maybe? I'm requesting advice here. I've looked at some water cooling projects, and one I looked at mentioned they would be using their PC as a LAN gaming PC mostly, so they were using 10/8mm hose, with compression fittings, since it would be more secure in transport, just need some info here. Not planning on much moving about, but I do sometimes have to move my case to clean under it, or decide to move thing around, etc. For now, just water blocks on the CPU and GPU. RAM, chipset and HDDs are just fine with passive, although I'm thinking of buying some replacement heat spreaders for the RAM, and maybe a small, low-ish CFM/dBA fan onto the chipset.. I've been looking for full-coverage blocks for the 3850, but I've only found one by EK. I'm not familiar with them, but I've seen reviews on their other blocks, seem to be good, so I guess this is the same. I'm wondering about how easily others have sold their g'cards, or full cover water blocks, after they were obsolete though, since I like to generally act like an arse and upgrade now and then even when it's unnecessary. Preliminary parts list I've constructed: 1/2" barbs all round - WatercoolingUK offers up free barbs with everything on my list, so I've chosen 1/2" nickel-plated all round Pump: 12V X2O Compact 400 £29.99 Radiator: XSPC RS240 Black £23.99 CPU water block: XSPC X2O Delta CPU £28.99 GPU water block: EK-FC3850 CF £59.99 Reservoir: XSPC Bay res - Silver £19.99 I'm going for a bit of a budget water cooling setup, so yeah, some of those things can be bettered, like the radiator, the Swiftech Black Ice II is good, but I doubt it's worth the premium. Same with the DD MC-TDX, which I really doubt is worth the premium, since the Delta was reviewed as being very good on a Q6600. There's no coolant on that list because I'm unsure about just which one to buy. I'm fine without colour in my coolant, but if I had to choose, a deep blue or a black colour would be nice, so any suggestions for this are welcome. For hose/tube, I'm also unsure. XSPC's tube is on that site, along with Tygon, and a number of generic ones, but I just don't know which one to look at. About hose clamps, what's best, I want a nice secure clamp, but something that doesn't require excessive force, possibly resulting in something being broken, to fit on. I'll be buying fans at a later date, but for now, I'll be keeping the stock Coolermaster case fans, which move a substantial amount of air, without sounding like a jet. Or else, I might fit my Antec Tri-cool fans, which are even quieter. I will end up buying some Noctuas later though, just haven't the need for them. If I find that temps are low enough as it is, I'd rather just keep the stock ones. For thermal compound, where the hell can I find that Noctua stuff that was recently reviewed by TPU, in the UK? If I can't find it, I think I'll just end up defaulting over to AS5. Also, what TIM cleaners do people recommend? I remember reading a review of the Arctic Cooling TIM cleaner (looking through the archives on TPU revealed some interesting reading actually), just wondering if there's something better, or cheaper. If not, I'll just buy that, since it's sold on WatercoolingUK, so I can get it with the rest of the kit. There's something else I'm forgetting, but I'll remember it eventually. Also, I know there are probably plenty of threads about water cooling, but I've just got to get my setup straight. This isn't like air cooling, which can be surprisingly easy to configure a good setup.
