Would this setup perform?

post #1 of 4
Thread Starter 
I am looking at building a water cooled computer. I have picked out basically everything that I will need but I want to make sure this will work. Here is a picture of the setup.


I know I spelled exhaust wrong in the picture. It was a quick sketch before I do a real mock up.

All vents and holes on the case will be covered with thin metal and there will only be an exhaust fan. The power supply sits in the case on its side with the fan facing directly on a vent that will not be closed. All components will be water cooled, the CPU, ram, hard drives, GPU's, and the motherboard has watercooling compatibility built in.

So the main question I have is will the system be cool with no air intake and only exhaust? Will it become to hot with no air intake?

I'm not clear whether your PSU fan will be acting in that capacity, but you definitely need some sort of intake so at least a little bit of air can flow through your case. Case temps aren't as much a big deal with watercooling as they are with air coolers, but having absolutely no way for air to come in isn't a good idea IMO. There will still be a little bit of heat released inside the case from secondary chips and components not covered by waterblocks, as well as from the tubes, pump, etc. from your loop. I'm not sure how fully you're planning on closing up every nook and cranny of your case, but as long as there are at least a few open slits or holes here and there for intake it should be enough. If for no other reason, your exhaust fan needs a supply path for the air feeding it otherwise it won't push anything.

I agree with everything threephi said. Unless every nook and cranny is sealed with a gasket or some sort, or with something like silicone caulking, air will always find a way in. But I do also suggest you leave something open.

Thanks for the replies! I think I will leave a spot for a 140mm fan in the front too. Then just run it on low speeds and keep the dust filters clean to keep the inside nice and dust free. I won't be covering every single spot that air could come in but the major spots will be covered. For the smaller spots like the cracks of the door I have some spare foam like tape (not sure what it is called) that I could put around the edge, but did not plan on it..
