1/4 to 3/8 adapter for radiator

Postby CapnMorgan » Mon Jul 11, 2016 12:38 pm

Hello all, I had a self contained cpu liquid cooling system and the pump failed so I dismantled it and want to use the radiator in a custom setup. The radiator is 120mm by 240mm but it has 1/4" (6mm) hose barbs. I pieced together a reservoir, pump, and cpu block but it all has 3/8" (10mm) compression fittings. I was looking through the koolance site and found that I can buy 1/4" compression fittings and just use 1/4" hose for the whole system, or buy 1/4" to 3/8" compression hose adapters and just reduce it to 1/4" for the radiator.

My thoughts are the hose adapters would be the lowest cost and least restrictive, but the use of 1/4" hose throughout would look better and be simpler.
Will the 1/4" hose be sufficient to cool an I7 6700k? I generally don't OC'. If so this is the setup I'd prefer. Or should I just adapt the hose right at the radiator? Or should I just get a Radiator with 3/8" barbs/g1/4 threads?

Your flow rates are going to be effected either way so if budget is an issue I would honestly just use adapters on the tubing right at the radiator. But the first change I would make it getting fittings for the radiator to bump it up to 10mm fittings (if they are removable) or outright replace the radiator and have 10mm through out.
