Replace CS PPC, CV PPC, Voodoo coolers

[easy_john]

Hi

Today I finished replacing coolers, to increase air flow in amiga 4000.

I will be glad to see your comments.

Good Job.
Thx for the ideas,i want to make this for my Csppc

Thank you.
I'm still looking for material suitable for making the final version.
It should be thin, but sturdy. As well as bend or securely glued.
Just think housing should make C-shaped, but not D-shaped, which will just cover the edge of the board Cyberstorm.

Cybervision is impressive a bit OTT but then again the more cooling the better.

can't translate this. a bit what?

WARNING! Recommended PPC chip should always have a fan ontop of the heatsink.

No, it should not.
Note - I have installed a big and _tall_ heatsink on the chip PowerPC. 60mm fan takes a big flow of air and blows it clearly through the radiators of both processors. At full load over the long term PowerPC temperature did not rise above 48 degrees.
This is a good choice of cooling when the cooling is qualitatively the whole board, simm memory, chips between simm, both the processors, and voltage regulator after the processor. You do not get the same using only cooling fan over PowerPC.
In addition, due to great heights radiator now you can't install fan on it.

having no fan on the PPC heatsink is high risk.

Absolutely no risk, because there is no difference, is the fan on the radiator or on the side of it, if the air flow is sufficient to remove heat from the radiator.
Сomputer is in a residential area where the temperature is always kept 22-30 degrees.

Since I have spent many years with computers, in that time I have used many different thermal pastes. I can say that most of them has a problem - too fast drying, which leads to the fact that the paste ceases to conduct heat and cause overheating. During the summer months is sometimes necessary to replace the paste on dozens of machines. I do not remember exactly, was there among them paste the ArcticSilver, but the mass of all the pastas are sold in computer stores dried up for 1-2 years. The only exception is the Soviet silicon-organic paste "KPT-8". I am actively using it for over 5 years, and I can say that this time it does not dry out even with round the clock work on processors with a temperature more 60 degrees. And work very well.

For the CyberVision's rams & your cooler :

I do not understand, why would I want it?

Too high price, i need it just for few photos.

my Bvision needs no cooling on the ram even at 100Mhz,above 100Mhz their start to get warm,but this is a on going project & will post when heatsink is needed when temperture is too high.

Yes, CVision ram cooling is not required.
In addition, the radiator is not a solid under the fan:


Most of the air flow goes to the left, through the cooling fins under the video chip, and smaller - down through the holes. that's enough, that would cool the memory, if I overclock it.


So there is no need to grind the base of radiator or underlay plate that would make contact with the memory.
