This system is already built and specced out to my satisfaction, so I'll skip the usual questions and pastebomb an info block here.
If you do have suggestions for parts that you think I should have, please let me know, but I am pretty set; just need cooling advice.
MOBO: Gigabyte EX58-UD5
PROC: Intel Core i7-930 @ 2.8 Ghz (currently; will push higher with better cooling)
RAM: 12GB Corsair XMS 3 9-9-9-24 @ 1600Mhz
VIDEO: EVGA GTX285 01G-P3-1180 1GB
HD: 1x WD 150GB Velociraptor (OS X 10.6 Boot Drive), 2x WD Caviar Black 750GB (1 for OS X Home Folder, 1 for Win7 Ultimate x64)
CASE: Antec P183
PSU: Antec CP-850
OTHER: 4 Nexus D12-SL Basic case fans
HAVE: Keyboard, mouse, speakers, OSs, etc...
Primary purpose: Run OS X as the primary OS for video transcoding, Virtual Machines, gaming, photo/video editing, coding, etc. Run Windows for occasional gaming. Ideally, I would like to have it be as quiet and understated as possible while still being beastly - I dislike loud/garish computers with side windows, turbojet fans, etc.
Hardware Goals: 4.2Ghz Core i7 @ 21x200, Memory at 8-8-8-24@1600Mhz, overclock the GTX285 (unsure of stable numbers yet, have not researched)
So, as you can see, I am building a hackintosh. I have it pretty well together except both of the WD 750GB drives arrived DOA, and their replacements are not yet here from newegg (I finished building the computer last week).
I started out with a Noctua NH-D14 aircooler, but when I overclocked the CPU at 1.3 vcore at 3.8Ghz where it was stable, I was running about 82C on one core and 74C on another core, even with the case door open and the fans running. I removed the cooler and redid the AS5 paste, but the temps didn't drop after about a day of burn in. At that point I began doing research and stumbled upon the idea of watercooling. I wasn't quite ready to jump into building an aquarium computer, but I did want to cool my CPU, and watercooling seemed the best shot. Additionally, I realized that I could cool my GPU, since it was running about 93C under FurMark, and sounding like a jet engine eating a lawnmower when I ran the benchmark. I RMA'd the Noctua, and am now doing research on watercooling before I buy parts. My goal is to hit 4.2 stable OC, so I can run a baseclock of 200Mhz and hit 1600Mhz on my memory. I would ideally also like to keep SpeedStepping enabled for moderate power savings (which may seem odd considering the amount of overclocking) but every little bit helps.
My current thinking is a Swiftech ApogeeXT CPU block, a Swiftech MCW80 + GTX285 full cover heatsink, a Swiftech MCR320QP-Res 3x120mm radiator+integrated reservoir, and a Swiftech MCP665 12V DC pump. Tygon tubing, barb fittings, more Nexus case fans for the radiator, etc. I am not terribly concerned about cost but sub-$400 would be great, since this computer is eating money faster than I can make it.
I am open to component suggestions, but am pretty sure I want the Swiftech ApogeeXT, at any rate. I am considering a ThermoChill PA120x4 radiator since it's apparently HSFBA, but I would need a different reservoir (which is fine - I had to remove the upper hard drive cradle in the P183 to make the GTX285 fit anyway, so I have space).
The radiator will probably get put into the computer much like this gentleman's did, since he has my case and a similar setup; I'm not using his components, but that's the best place to put the radiator. The fans will mount underneath in a push configuration, both to maximize cooling efficiency and reduce noise. I would cut the case in a similar manner, and build/bend/buy a shroud to make it blend into the top of the case nicely.
My questions are these:
1) Are either of the radiators going to do a good enough job with a Core i7 OC and a GTX285 in the same loop? The Tom's Hardware Watercooling Basics post indicated that one 3x120 radiator is probably not going to be sufficient, since the Core i7 is a hog and so is the GTX285. I am unable to find much corroborating information about this, though, which is one of the main reasons I am posting.
2) I am going to be running distilled water in clear tubing; color/looks are not important to me except that it be neat (you should see my cable management). What additives do you recommend to keep gunk/algae down? I am planning on cleaning the system once or twice a year, but I was thinking that 90-95% distilled water + 5-10% Swiftech HydrX would be a good solution. (I don't need or want UV reactive coolant but I've heard good things about HydrX in general - feel free to talk me out of it). I am also considering just using a Killcoil or two - I'm not vain but they would look pretty sweet when pulling the side of the case off, and they apparently work pretty well.
3) Thoughts/Comments/Critiques/Questions/Concerns/What you would do differently for the watercooling setup?
4) Why does Core 1 on my CPU run consistently 8C hotter than Core 4, and ~5C hotter than Cores 2&3?
Thank you. I eagerly await your replies.
