Change the loop so you go pump-cpu block-flow meter. The original kit pump should have moved about 1.75 gal per min.
Confirm good block to cpu contact.
10C over ambient a idle is not good results.
Are you pushing the warm case air thru the rad or pulling in cooler outside air? Those xfired gpu's probably has case air at least 30C.
What will changing the loop do, iv heard it makes not much difference in temps at all, or are you trying to rule out the flow meter being a restriction? Cpu to block contact is good, reseated it again yesterday, I use the pea method, I trial fitted, checked spread was good, cleaned off, re apply and seat permanently.
The new pump is 800lph.
Maybe my flow meter is a heap of crap and causing a restriction.
Ill have to wait till next week to change the hoses, I don't have enough here to re-route them or enough coolant. Even in the res, the coolant isn't very turbulent at all, I thought it would have been moving a lot more. Is it worth removing the flow meter and testing again? Or maybe the way iv connected to the meter, Inlet through right side and outlet through top? (check the vid i posted)
I'm pulling case air though the rads, although the case has good airflow in and out. The GPU's do get pretty warm as well, i have setup a manual fan step up for them so they stay a bit cooler, most of that warm air vents out the rear of the case aside from the radiant heat obviously.
What are load temps on the new pump?
With the fans running at 2500 and Prime running for 15 mins, Core temp says nothing over 80 centigrade. And its probably about 28 centigrade in the house atm, its a really really warm day! That's with the side cover off. Watching the temps, it really doesn't move past 80, more between 75 to 80.
Thanks for all the replies too lads!
