I want too use two 240x120mm heat exchangers to cool an I7 processor and a HD 5970 video card along with PSU, memory, SSD, and mobo...I was thinking about doing the processor, memory, SSD, and mobo on one radiator. Then the 5970 and PSU on the other radiator. Would this set up keep temperatures around 34 C under load? I will also have air cooling but i want too keep all fans in use on the lowest setting for little to no noise. Also what heat exchanger thickness should i go with? 30mm? 33mm? or 46mm? The radiators will have 120mm fans on them pulling air through the radiators. The radiators will also be mounted externally somewhat like Puget Systems used for their mineral oil submerged computer. Thanks!!!!
Most transport airplanes have air cycle air conditioning packs - Some airplanes have freon (R12) air conditioning units - The passenger 747 has 3 air cycles packs of which 2 are normally used during cruise to cool off and supply air to the pressurized area - Many cargo 747 only have 2 air cycle packs (the third pack is often suppressed in converted passenger airplanes) - The bleed air required to operate the packs comes either from the APU (on ground) or from the engines (during cruise) - Bleed air taken from engines during takeoff reduces the thrust available from the engines, so you might hear about no pack takeoff in which the air conditioning is not used during the takeoff and initial climb - This is done when extra power is required - On the 747, the APU can be used for bleed air to the air conditioning packs during takeoff, so it does not reduce engine power - Heavy passenger loads - i.e. 500 passengers on board of a 747 - have high requirement for cooling (despite outside cold air) - since each human body heats up the cabin air with the equivalent heat of a 100 watt lightbulb - All DC-8 airplanes have two freon air conditioning packs - On the 707 the two packs were either freon packs or air cycle packs (option by customer airline) - All 727 and later Boeing airplanes have air cycle packs - Air conditioning on small business jets (Learjet) a freon unit is used - .
i7 and 5970 at 34 under load...I dont think so. The best you can manage is to keep it under 40C under load. As for size, 36mm should be more than enough to sustain. Air cooling is not the key here. A fan for hard disk and the radiator at low flow(30 Cubic feet per min) is more than sufficient to keep the noise at bearable levels.
