Hi
I've purchased a vintage harddisc recorder, and I would like to make it sound less like a jet taking off. The device was meant to replace 2" tape machines which where in their own room anyway. So I guess fan and drive noise was less of a consideration back then. And yes, the audio quality of the recorder does justify this project.
I've ordered an SSD IDE drive to replace the system disc.
I've ordered a SCSI to SATA converter to replace the audio disc.
I would like to upgrade the CPU cooling to something less noisy.
It is an MMX 233 MHz CPU in a socket 7. At the moment, there is a 50*50 mm heatsink, and due to capacitors right next to the socket, I will not be able to fit a 60*60 mm heatsink. So I am thinking more in the lines of a taller 50*50 mm heatsink and a less noisy fan.
But what to choose and where to find it? Do you have any recommendations? My budget is probably within the 150 $/€ range, if it takes something exotic to get this as perfect as possible.

Re: Vintage quiet - in search of a good socket 7 solution
First of all, I think socket 7 uses the same mounting mechanism (you have to double check) as AMD's Socket 462, or socket A (the ones that doesn't utilize mounting holes).
Socket 462 was used for a long time, at least until 2004, so it may be easier to find parts from such systems. Dunno if that's of any help tho.
Your CPU has a TDP of 17 W, so it doesn't need much cooling to begin with: http://ark.intel.com/products/49967/Int ... 66-MHz-FSB
I think you're going to have a hard time finding a quieter 50 mm fan. If there's room for it I'd go for a 60 or 80 mm fan, even with the same heatsink (if the capacitors doesn't make it impossible).
In some situations it's possible to mount a 60 mm fan directly onto a 50 mm heatsink, you just won't be able to secure with all four screws
Noctua has a 60 mm fan: http://www.noctua.at/main.php?show=prod ... g=de&set=1
Here's a list of other 60 mm fans: http://geizhals.de/?cat=coolfan&xf=355_60~356_25#xf_top
Assuming that there's room enough above the CPU, you can look for a fan adapter (funnel) like these: http://www.frozencpu.com/cat/l3/g47/c12 ... Page1.html
Otherwise, you have to make one yourself, possibly by salvaging the frame (removing the motor from your current 50 mm fan), put it together with a piece of plastic with conic shape (maybe part of a kitchen funnel), and finally a 60 or 80 mm fan.

The old Pentium MMX 233 was the only Pentium MMX to come with a fan, the 166 and 200 just had a passive heatsink. Due to the overclocking potential there was with these chips I highly suspect you could run a 233 passively anyway. Unless you have no airflow through the case it should be OK.
You can't use a Socket A or Socket 478 heatsink as they do not have a large enough flat area. These chips had a physically enormous contact patch of 50mm x 50mm.
You could find a big generic heatsink from somewhere like RS Components that happens to be the right size probably.

You're right. Although I wonder if the whole lid of the MMX really have to be covered anyway, the chip is much smaller.edh wrote:You can't use a Socket A or Socket 478 heatsink as they do not have a large enough flat area. These chips had a physically enormous contact patch of 50mm x 50mm.
I'm not sure that generic heatsinks are that easy to mount, those plastic mounting tabs breaks off easily.

I think I've used socket 370 coolers on socket 7 CPUs. Last time I played around with a Pentium MMX I could make it run very cool by underclocking and undervolting. Easy with the motherboard I used, but that might not be possible with a vintage harddisc recorder.
Perfect would be if there was a way to replace all that old hardware with a Raspberry Pi.

viewtopic.php?f=8&t=63014 (or similar) then use any heatsink you want on the other end.
