Heatsink/fan for 68040

[som99]

Even better then thermal paste + super glue is Arctic Silver Thermal Adhesive, it's as it name implies a thermal paste that harden as glue and stick the heatsink on there with thermal paste properties, I use it as a mad man on many things since it works great.

A knife and some tinkering to get the heatsink of if you ever want and then just acetone to clean the heatsink/CPU from the thermal adhesive off



Ive used this for quite heavy coolers on x86 PC's to fit CPU coolers that where for different sockets and it works like a charm!
Ive also used this for all things I want to put heatsinks on that has no mounting holes like vRAM, mosfets etc

time to modernize
 this doesn't need a fan

Uhm? Do you honestly think it's a good idea to rest 730 grams on the CPU board? Then remove internal drives + the drive bay and the PSU to fit that giant cooler then he needs to make a 15cm hole in the top of the case to fit it and loose the ability to have a monitor on the case.

Does that sound practical to you?

yes,you can modify the fan to fit in the case using this

the most important thing is the base of the cooler and the pipes
such cpu' coolers supports up to 95w cpus,work even on core I5 sandy bridge processors
imagine it ...the 040 dissipates only maybe 10w,you need less  of a quarter of such heatsink

But then why even bother with those fan less behemoth if you are going to destroy it? They are expensive and designed to work as is, why not just take any random modern cpu cooler with heatpipes for a few bucks and modify them instead? I don't know the heat output from the 040 but I bet you could do it fan less with far easier methods.

Also id rather have a low noise 13dB fan on a small heatsink because then I know it will not run to hot without risking anything. Also a small 40mm low dB fan will not probably be noticeable outside the chassi, the PSU fan likely sounds quite a lot more, so why bother making a fanless solution?

I don't know if you have used Fractal Designs silent series 40mm fans, I have and own over 10x of them and id put hands down you wont hear them outside the case.

Edit: @Oldsmobile_Mike - I would get a small fitting heatsink, VGA/Chipset ones can be found in copper, then put a low noise fan on like this one and you be set

Looks exactly like mine. Had do the filing of the floppy tray base and leave the lid off too. I'm running mine at 5v, much quieter and no crashes I can attribute to it yet. Need to look at a power supply fan option now. Way too loud.

is it a 80mm or 92mm fan in the PSU?
If 80mm and 19.46 cfm is enough ill say a Fractal Design Silent Series R2 series 14dB fan.
If you need to move more air ill say the Noctua NF-R8 hands down, 17dB and 31,2 cfm airflow and it's a Winner in the 80mm class for me.

if 92mm fans same applies either Noctua NF-B9 or Fractal Design 92mm Silent Series R2.


I would pick a non PWM fan from Noctuna for a PSU to be safe, they are of great quality and last forever and they are preforming good while keeping quiet also their color scheme somewhat fits old computers
