Using a fan larger than the Heatercore

[sunrunner20]

I am considering using a single 172mm x 150mm x 51mm fan on my Heatercore for watercooling. The only problem is that it is wider than my Heatercore. How Should I mount the fan? Use my case as a shroud? Make a shroud that opens wide instead of closing in?

Make a shroud. Make it atleast 4" deep for best performance.

or get a 2-352 heatercore, I had one sitting on shelf and it would fit a 172mm straight side quite well. I,ll grant you it's an ackward core to place and the inlet/outlet are 5/8"(one is actually 3/4" but with very little cutting you can take off that part).

Not changing heatercores, this fan will be an "extra" if I do use it, In fact I am considering a configureation where the fan would be at the bottem of the case, sucking in air. But, that would probally cause major problem with tempature in things like my PSU that want nutral or posative pressure.

Why would it cause problems with your PSU? Having another intake would probably improve temps across the board and possibly make your PSU rails a bit more stable even. Besides, PSUs can tolerate a wide range of temps so I wouldn't worry about it.

If you have the time, you can fabricate a fiberglass shroud. That'd be the way to go.. I used to have a link to a good guide, but alas I can't find it anymore :( A trip to Home Depot for some fiberglass resin, sandpaper, paint, paintbrush, cleaner, then pantihose material... put 'em all together and voila! A nice shroud. Easier said than done, though if done correctly, will solve your problem.

Or you can just buy two Panaflo 120mm fans and be done with it ;)

A simpler shroud might be to just buy some sheet metal and cut it into the shape necessary. Just a thought.

It would cause problems becuase this fan can create more pressure than the fan in the psu can handle, but likely only by a bit. So, my WC fan would creat negative pressure, while my PSU is trying to vent air ouside. The psu would get hot, turn the fan on and creat a big problem, HEAT!
