CPU/GPU block flow direction. Does it really matter?

I know CPU and GPU blocks have in/out ports but does it really matter which way the coolant flows? I ask because if I could reverse the flow duration on my GPU block it would really help my tube layout.

Bykski for Zotac 1080ti Amp/ Amp Extreme. It was fine but now I've mounted the GC vertically to show off the GC block I'm going to have to change the routing. If I could reverse through GC it would but I don't want to lose any cooling efficiency.

The left channel is flow in.

Similar to an EK GPU block, the difference will be 1 or 2 degrees at most on your core. It's only really down to when it hits the VRMs I think. If you use the inlet, it goes Core > VRM. If you use the outlet as the inlet it goes VRM > Core (I think... I maybe wrong, it's something like that anyway!). I wouldn't worry too much.

Cheers. I'll give it a go. I'm miles from temps being as issue. GPU under full load boost @2073ghz is 54c

Well I've switched to hard tubes, only cocked up a couple of bends which I'm guessing isn't too bad for a first attempt. Am pretty chuffed with result. As you all said hasn't made any real difference to temps, well maybe a couple of degrees higher, full load for 30 mins in Heaven Bench and GPU sat around 52c with a max of 56c. Had to tip the case around a bit to flush air from GC block but other than that all good.

Temps update. After 90 mins of of playing BF5 the GPU hit a max of 65c and CPU 64c. Still ok considering its only a 240mm x 60mm rad for both. Thought I'd have to invest in a second rad. Maybe when summer comes around.

Its XSPC EC6 Opaque White with XSPC UV Yellow dye in it. The yellow is a great colour with UV off as well.
