My main worry would be if the block and heatsink aren't mating correctly then doesn't that mean there is a risk the gpu core and the block won't mate correctly??
If your core temps are fine shouldnt worry, but worth checking your VRM temps, as thats the part that will be most effected as in theory its heat isnt being soaked up by the water block as advertised.
They should of counter sunk the blocks screws on the cold plate or just used thermal pads which would of been 100% then no contact.
*** lifted from Blog and isn't as clean as Sky-ways but should do the job
started to get to work on the Hybrid cooling, but whilst the card was out i had a chance to add some heatsinks 20mmx20mmx5mm to the Pro 950,
All laid out
As with the previous post, i needed to trim off more and had to get the width down on the block by rooming a fin from the top and bottom, to do this i had to take out the waterblock from the heatsink and came across this
That indeed is a lot of paste making NO contact with the heatsink. Alphcool advertises the whilst the block isnt fully watercooled, the plate can transfer heat to the block to be cooled down. looking at this I can see why users have been monitoring high VRM temps. In theory is a perfect idea but the execution is poorly lacking, so be warned with the Alphacool blocks !
top side up, fits like a glove!
Correct way up, will need to trim the bottom left fin just to make sure it clears the mount point
From this image you can see the Ram will need to be trimmed off. i Though about trimming down the fins but still won't work and dont want to cut the memory plate section and just easier to cut the ramp, and plastic glue back on in future. You can also see with the heatsink, theres plenty of height clearance too
quick poor shot of the heatsink over the current board, trimmed the pin header section to allow the fan to connect.
Hope tonight to mount the whole thing together and attach the red LEDs to the fan section to light it up.
With the second card i'll just use the universal alphacool mounting without the heatsink and use some heatsinks for ram chips.
