Have been pretty bored lately, so I thought I'd have a look at my old Super Orb that was removed from my system due to lack of performance.
I pulled out the fans and then seperated the base from the round fin section with a hydraulic press. I lapped the base and then gently pressed it back together with Arctic Silver between the surfaces.
Not that I think that the previous work had much bearing on the outcome of my experiment, but like I said, I had nothing else to do.
That fan that they mount to lower/inside of the unit must surely be the reason why it won't dissipate heat, so it didn't go back in.
Instead I decided my black label Delta would come in handy, but fastening it to the top would be pretty hard. being an experiment, I opted for insulation tape, and continued to wind it down the outside of the fins, leaving about 12mm gap above the top of the heatsink base. I figured this may create kind of a tunnel, ram type effect with a gap at the bottom to expell the air.
I fitted it to my CPU and ran some tests.
I was running about 37degC at idle with my FOP38 heatsink and coolermaster fan, with all my case fans at idle = no load.
With this thing, minus my ducted CPU case inlet fan, I was down to 34deg, running Prime 95 endlesly and netsurfing it maxed out at 36degC.
So I put my 17CFM Coolermaster onto the ORB and it runs no more than 39deg.
With the intact Super Orb, my temps used to get up around 43deg at idle!
My conclusion is that the heatsink design of the Orb is OK, it's just the crappy fans that they fit.
