Hi, Sunday Update.
Today I will make some heat sinks for HD4850 memory chips and power mosfets.
So first start with Memory chips. So here is the raw material.Heat sink from old PSU.
After few minutes of working it looks like this
Now for Mosfet cooler
After few hours.
Now let’s place them on card.
That done. Now install the card and connected the block to the loop and filled the coolant.
Now boot it.
GPU ideal temp is now 38c cool hey but memory seems to be hot at 77c on ideal. The small heat sinks are not sufficient for the memory chips. So added 1.5mm thick copper plate, this done the trick.
Now at ideal system
GPU is 39c
Memory at 41c
CPU at 34c
After playing Bioshock 2 at 1920 x 1080 for two hours.
GPU is 47c
Memory at 49c
CPU at 41c
COOL…. I think I have a nice temperature for my rig. Will try to OC GPU now. Have a look at final mod.
Will keep you update.
Thanking
