GTX 240 too restrictive for X2O 750 pump?

post #1 of 14
Thread Starter 
I impulse bought a GTX240 after performance pcs told me the Magicool 480 I ordered yesterday was out of stock. Now I'm wondering if the Black Ice GTX240 is going to add too much restriction to a system that currently has an RX240, Rasa CPU block and XSPC 5970 GPU block.

The reason I wanted another radiator was so I could use quieter fans and maintain temps similar to what I'm getting with a single 240 rad with 1600rpm fans.

just run it on air, if your using it for physx, its not going to get hot at all.
EDIT: and yea, it will add allot of restriction onto the loop.

That is a very restrictive radiator, you'll be pushing the boundaries of the pump. The GTX series radiators have absolutely horrendous restriction compared to most radiators, with a little over 1 PSI vs the 0.10-0.25 of most radiators.

If you can I'd get any other 240mm radiator, as basically any another radiator offers a lot less restriction.

I was thinking about getting the GTX360 version of that RAD.

I also have that pump. Would a SR-1 360 be a better choice?

Not by much. People expect too much out of that little pump; if you're going beyond what was provided with the kit, then you need a better pump to match.

The added 0.1-0.2 PSI drop from a good radiator isn't really going to affect the pump too much. It does put out 3.69 PSI, so it can run 2 blocks and 2 radiators pretty easily as long as none of those parts are particularly restrictive (AKA no EVGA or Aquacomputer blocks or GTX radiators).

Run the EK blocks in parallel and you will be totally fine.
