I'm thinking of changing about my fittings to tidy things up as at I've got a lot of long bends in my loop which I could sort out with a few angled fittings.

So my question is can I use multiple fittings to create the angle I want?
e.g. Radiator -> 90 degree -> 90 degree -> 45 degree -> barb -> tube.

I'm sure I've read on the forums that its fine and doesn't effect the flow rate.

I found a phoyba 180 Degree Variable Fitting and was wondering if anyone has any experience with it or should I just use 2x 90 degree.

Also whilst I,m thinking about it.
Is it OK to have 2 Radiators with fans in the middle and no spacing/shrouds or would this cause issues?

I did a lot of research on the effects of 90 degree fittings and found out many saying it would effect 1 C per 90degree fitting and 0.5C per 45degree fitting.(WIll add the link later if I can find it - but I am sure it was in skineelabs or martins)
many also saying if you have a good pump it would not matter much.
I have changed my loop by removing 2 x 90degree fittings and 3x45degree fittings and a 240mm RAD.
So hoping this would effect the flow rate. Could take couple of weeks to find out the results as I am waiting for some more stuff though :D
 
Well i plan on moving 2 rads together in series but the fittings will either face each other or be facing the same way so id need a way for the fittings to enable me to send the tubing over the 2nd rad.

Dont see how a 45 degree will change flow much as it just altered the direction slightly but a 90 degree so me seems it might.

I would just need to enable some clearance over a 2nd rad in close proximity.

How many bends do you think are in a radiator...........

I can guess many but im curious about the multitude of fittings I would be needing.

Multiple Fittings?
Excuse my Paint skills lol.
If you can get excuse the drawing you might get what I want im getting at.

The black is from pump tube -> 90 degree -> New Rad -> 90 degree -> 90 degree -> Dark Grey tube -> 90 degree -> 90 degree -> Front Rad -> 90 degree -> 90 degree -> Light Grey Tube -> Rest of loop.

A lot of angles which is why I'm asking as it looks to me its flow limiting but its possible I'm wrong.

If you haven't seen my build I'm using a D5 pump.

Radiator Spacing?

Which is best?
  • Leave as in diagram no spacers.
  • Spacers where fans are and move fans to the new Rad.
  • Add in more fans on new Rad.

That would work :)

Although, i'm sure it would be better to get some flexible tubing (tygon) and 45 degrees

Some anti kink coil aswell?
 
Test your angled fittings well. I had 45 degrees in my first build, and 3 of the 6 would leak if the pressure wasnt perfect - not water pressure, hose direction or finger pressure.

They can be used to great effect in tricky bends, but sometimes they can be a pain to get just right.

You may find heating your hose up in hot (not boiling) water will help get round tight bends.
