PM6100/390HPV

I got a 400Mhz G3 Sonnet card instead of trying to swap the oscillator.  It runs at 390Mz which is fine with me.  I also bought an 8100's HPV card (w/4mb) on a whim. 

I have moved the hard drive to the middle bay to make room.  With the lid on the temps spiked to 62*C+ while not doing much.  I took the lid off and propped a fan in the hard drive bay.  It is now down to a stable 54*C so  I am going to have to rig up something.  Might try to slide a fan under the hard drive bay since there are some vent holes there.   Not sure how this air is going to get out though?  Maybe I can find a horizontal 3.5in bay fan or a 5.25in fan set to put in theCD bay and leave the CD slot cover in place to let air in.

I was also going to fix my LCII with a Q605 or P460 board, but I lost those eBay auctions.  Guess I will just recap the board and go with the 25Mhz accelerator I have. (The LCII+ ???)

Re: PM6100/390HPV

Tough machine to cram a lot in. Still, the interior should not get nearly that hot -- I've got a 6100 with a 300MHz Sonnet (though using motherboard video), and it's nowhere near 60 C. Where are you taking the measurement, and with what? What type of hard disk is installed?

The hard drive is the original Quantum 250MB.  The way the VRAM on the hangs off the HPV it is right over the ROM SIMM and 601 heat sink.  Pretty much makes the G3 closed in a little box. If I can find the right fan, I could direct it right down the tunnel and have clean air coming from under the HD bay.
