BlizzardPPC flash update problem.

[x56h34]

I've had a Grex 1200 before, when it was still neck to neck with Mediator (my old Power Tower 1200 BPPC 060 setup), and it ran perfectly well.

I would assume that those dead Grex boards and PPC cards were most likely killed due to usage with BPPC 040 cards. Now, before I actually got one, I assumed that Lempkee was exaggeratting about their heat problems, but boy was I wrong. A BPPC 040 has got to be the hottest Amiga product of all, and I mean this heat wise, not hot as in good or cool! ;-)

I will need to implement some major cooling for this. The 040 will get a 486 heatsink and fan, and I may as well put some sort of an extra fan over the PPC heatsink. I just need to find one that can easily be attached and is the right size.

You could do a lot worse than getting a VGA cooler to bold onto the heatsink.

GadgetMaster got hold of one for me, a VanTec IceBerq 4. It has a low profile, is wide enoough to cover the ppc heatsink and has a solid copper construction.

It also comes with a few small copper passive heatsinks for chipsets and thermal pads to stick them on with. I used 2 cut in halld to secure the main fan (it weighs 77 grams) and some thermal paste between the base of it and the surface of the PPC cooler.

It runs at 6000 RPM and keeps the thing nicely cooled. The original fan is totally redundant now and I'm thinking to detach it as it is a chronic source of dust building up inside the ppc cooler. You really need to keep an eye on that side at least, the dust can kill your ppc.

As for the 040, I have a passive (but hefty) heatsink bonded to it. I have shoved a temperature probe into it and have yet to see it go over 32 deg C.

@Karlos:

Sounds good. Do you have any pictures of all that, by any chance? :-)

I had no problems with the G-Rex so far but my machine is
well cooled.
The only problem I ever had (and still have ) is that the
BPPC was damaged when a PSU died, so PPC OSes do not work
with the G-Rex anymore. The BVPPC (which uses a static
PCI addr) works fine.

Not of the thing installed (don't have a camera handy), but the fan itself is here (site requires flash).

Look at the system cooling section down the page and select VGA card/CCB-A4C.

The temperature probe isn't a permanent thing, I was just monitoring it to get an idea. Currently it's 29.2 deg C on the 040 heatsink, but if I measure the PPC heatsink (a bit fiddly) it's actually about 20 deg C with the fan going.

Thanks! :-)

@SWAUG

That's not exactly the same model but very close. As far as I can see, the only differences are that this one seems a bit larger diameter and has "go faster" blue LEDs :lol:
