update.
i have quickley polished the sides and sealed the base and barbs.
was in process of lapping the base and i have took most of the skin off my thumb and finger so i have had to stop for tonight.
they are so saw and wont stop bleeding.
i will go with the 1/2 inch brass pipe for the lexan top and also change the outlet of the pump too.
i need a good way to test this block and was thinking of the following.
1. standard intel heatsink.
2. koolance exos
3. new block
on each test give them some time to settle down
make sure room temp is as close as possibe before each test.
then meassure at idle temps.
run setti/prime or sandra burn in for lets say 1 hour . measure load temps and monitor room temps too.
what do you think will this give a good indication on how good it works as we know how good the hsf is and also the koolance.
