90 degree fittings - consequences (90 degree on pump outlet)

post #1 of 5
Thread Starter 
I use a few 90 degree fittings in my setup, for example two of them are connected to the outlet of the gpu waterblock.

I am wondering what would be the impact on using the 90 degree fitting on the pump outlet - would it increase the temperatures dramatically? Or would the current 90 degree fittings make little to no difference to the performance of the loop?

Pump is MCP 35x and fittings I use are the EK rotary 90 degree fittings.

I have a bitspower rotary 90 fitting after my 655 pump. Havent had an issue. I even use a 1/2" barb and 7/16 tubing with no zip ties or clamps. No issue one bit thumb.gif

Cant say if it affects temperatures or not. Best way is for you to test it out yourself biggrin.gif

Reduced flow will actually keep the pump from overheating, not the other way around. Using a few 90s makes little impact imo, I wouldn't worry about it unless you used 90s everywhere.

Outlet shouldn't matter much, it is the pump inlet where you should avoid elbows if possible. Inlet elbows load the pump impeller out of balance so that's why it is more of a performance loss there.

What if you have a T fitting about four inches before the inlet? Is that a nono?
