I took a gander at the PA120.2's data on Thermochill's website, and found a graph for a 10c temperature differential between coolant and ambient. At 1.9gpm, a PA120.2 can dissipate about 350w with some Delta 1212M fan, around 37dB. Congrats to myself, I can read a graph.
After browsing the phase section, I came across jinu117 stating that an overclocked Penryn QX9650 puts out around 175w, +/- 10. Thats pretty darn good considering its an overclocked quad.
Sometime next year, Im planning on a decent system overhaul, G92 GT or GTS, along with a P45 motherboard and some type of Penryn due to Nehalem's probably astronomical price. Probably a dual core, E8200 or 8300 just to play with. Keeping in mind that the overclocked quad core QX9650 puts out about 175w, the dual core would put out how much heat? 120? More, less?
On top of that, the G92, and even G80 for that matter, dont put out as much heat as my G70 7900GT does, or atleast I dont think so.
A chipset cant put out that much heat, less than 20w I am guessing.
Totalling all that up, for my future system overhaul, thats what, 120 for the processor, 20 for the chipset, and lets say 150 for the videocard, all are +/-10, for a grand total of about 300w, which is within the PA120.2's max of 350w @ 10c temp differential of coolant/ambient given the Delta fans.
Come December, Im planning on getting some Deltas when Sidewinder gets them in stock, somewhere in the 120-140CFM range and tossing them on my Sunbeam rheobus and getting them down to a decent sound level. They will go on a future PA of mine, be it the 120.2 or the 120.3... as I see it, I would only need the 120.2.
Given my current setup, very early stepping E6600 @ 3.0 @ 1.375v and the 7900GT, no chipset cooling in the loop, I would probably be around 300w as well.
I know the PA120.3 is much better vaule, given what, $15 more when Im already spending $115 on a radiator isnt much for much more headroom, but Im really thinking about the coolant/ambient temperature difference. The more radiator, the less difference, I know. Silence isnt too much a deal to me when Im using my computer in the dorm room - either the TV is on, Im playing music, or playing Battlefield 2, so sound isnt a problem unless its 50dB. At night, system could be left on and thus, go idle and I could turn the fans down lower, or off most likely.
Back to my figure of 1.9gpm, thats a rough estimate. Probably a DDC3.2 + Petra's top, Fuzion CPU, MCW60 and maybe an MCW30, t-line, some PA rad. I was thinking about the Fuzion GPU block, which drops it down to about 1.45gpm, which is still decent. I like the look of the Fuzion GPU, but like how the MCW60 handles pressure drop. Price isnt really an issue.
At any rate, now that Ive looked into it, can anyone tell me where my logic is wrong, or if Im good to go with the PA120.2? 120.3?
I know the standard response from everyone is "PA120.3 or MCR-320, D5, Fuzion CPU, t-line, MCW60, no chipset", but is that really right? Can the PA120.2 handle it? Granted the PA120.2 performs the same as the MCR-320, I just want the PA120.2 due to pressure drop. And because its a PA. :cool:
Advice, please? Long winded, I know, but I just ate a ton of candy before bed and Im not tired.
