JBJ aquarium chillers

Considering one of these aquarium chillers. Would the 1/15hp be sufficient to cool an i7 and pair of gtx 290s? Also, is an MPC-355 enough to pump the water through it?

1/15 hp

no bro

1/15hp really isnt much.

how much power is required? the 1/15hp is the smallest, but they also have 1/10, 1/5, 1/3/ etc. they get expensive and large at that power level. It seems like it would be overkill for a pc. Removing around 400 watts of heat from around 100ml of fluid?

I used those for salwater tanks.....they are good for maintaining temps at about 78F........thats about it.

Let's use our noggin for a second. You want to use a fluid, in this case water, to remove heat from your PC. You mention a Core i7 and a pair of GTX290s. GTX290s don't exist so I'm going to assume you meant GTX295s. The CPU when overclocked will be in the range of 200w and each GPU is something like 250w, so you are looking at 700w of heat. Adding 700w of heat into the water requires removing 700w heat from the water somewhere else or the temperature of the water will increase.

So in closing, unless your chiller can remove maximum load I would suggest sticking with air or traditional water cooling. There are chillers that can handle this load, they just are large and expensive.

sorry my cards are actually gtx 280, so far less wattage. My PSU is only 650w so I'm sure total draw is under 700. My i7 @3.8ghz (1.2v) is producing ~155w according to hwmonitor.

I'm currently using two 120mm rads and the system will approach 80c at load. I thought that a chiller might be more effective at removing heat than rads. I guess that's not the case?

You guys building chilled water setups, do you use rads as well and chill in a separate loop or does the chiller dissipate all of the heat? I have a dual pump dual res and two loops so I could definitely keep the rads and use the 2nd pump to circulate the chiller. Is there a rough correlation to hp and the amount of heat in watts it can remove?

The chiller dissipates all the heat and typically below ambient temperatures.
