Overclock Warehouse Ofrio
If you're wondering what the heck Ofrio
means, I'm told it's "The Cool One" in Portugese. ;) Designed as a highend
solution for AMD SocketA cooling, it is also compatible with Socket370, and
rubber feet are supplied, as well as a fan header adaptor (you wont want to
power THIS fan from the mainboard.) and heatsink compound. The Berquist type
pad, I have been informed, will not be on shipping units. At least it was one of
the easiest to remove I've ever seen. :) You can see from it's layout, that it's
design is similar to the PEP66T, with a sideways mounted fan, and a copper
baseplate. Beyond that, they are greatly different. The Ofrio is a decent bit
taller than any of the other heatsinks, except the SuperOrb. Equipped with a
38CFM Delta fan, it's also far beyond any other single fan here in the CFM
department, as well as considerably louder. It uses bonded thin-fin aluminum
fins that are weld-bonded both to the full length copper base, and the top of
the non-removeable shroud. As the most massive sink, there is a downside. It
would not fit on two of my Socket370 boards (AsusCUSL2, Aopen AX34-ProII) at
all. This, and the difficulties with the SuperOrb, are what led to my two-stage
testing as you will see.
Testing - In two parts.
I do have a couple of Socket370 boards lying around that the Alpha PEP66T
(without flipping the shroud & fan) and the OverclockWarehouse Ofrio would fit
on, but neither are overclocking friendly at all. Stable boards, but not
overclockers. Also, I dont currently have a SocketA system in-house (I *MUST*
correct this situation ASAP!. note to self) at all to fairly evaluate the
Thermaltake Super Orb. Certainly testing and measuring temperatures on a non-overclocked
processor is valid to a degree, but I would still be unable to really torture
the heatsinks, and see where they become unable to dissipate a high thermal
load. So, I turn to a method I've used before, and indeed seen used before. The
part 2 tests will consist of running the heatsinks on an artificial thermal
load, a 72w peltier, and measuring coldside temperatures. The better dissipation
of heat should yield a lower coldside temperature, and should give an indication
of the ultimate potential of each heatsinks, regardless of it's socket
application.
