Avalon after air flow mods.
As you can see in first pic using the cable to hold them in place as plenty of ribbon to use to make a little fold to hold plastic sheeting in place and where the molex connect theirs about a 0.5 to 1.5ml gap to allow to create a curve for the plastic to be molded into shape to allow to curve around and make the mod fit and old in place.

On this picture you will see where at the top this is still covering the gaps and also where air flows so I needed to push future to allow air flow to flow through the heat sink as I was a at first blocking this so had to gently guide it through and make marks on it where to mold curves in for cornering.

Temps before and after more or less the same but not using as much fan power and after mining 24 hours sold this is running nice and cool with oc to 84GH also fans never go above 1800 now so lot better results still doing other mods in time to it to get better air flow. This is with no extra fans added maybe get even better results with some delta fans in but their too noise

Have also taken unit upto 90GH however too many hw% errors however temps solid 50c so not doing too bad. Also added new 860w corsair digital psu working perfect never takes over 730w
Currently fan never goes above 2400rpm and after a few hours of feeq range increasing to max setting fans sit at 2200 to 2400
