Flow to temperature

[robmac65]

I have just changed my xspc x20 750 pump/res for EK Water Blocks EK-D5 Vario X-RES 140 (incl. pump) but my temps have gone up under stress from max @ 51c to max now 56c.

I have the d5 set to 4 and it seems way more powerful but can a faster flow rate actually make the temps go up?

My reasoning is that as its flowing faster then its not spending as much time in contact, is this possible?

I have not changed it to slower to try as it means taking mu gpu out and i cant be bothered just yet lol.

I think i have sussed it out anyway, simple really, the tube res in now mounted above the gpu and because of that the heat its throwing out is increasing the water temp whereas before the bay res was further away and in a bay cage so it wasn't affected as much, god damn,so it looks way better but poorer temps or looks not as good with better temps .

Looks like i need another rad to lower the temps again , looks like i have made the wrong decision, should have gone with a d5 and a monsoon!

Well I lowered the pump from 4 to 2 and the temps have dropped down 6c, so then to be sure i put it back to 4 and it went up again dropped it back to 2 and it dropped again, make of that what you will.
