Some of you oldies may remember my original CoolJag from like 20 years ago, where I stuck a couple of small fans on top of Tom and Jerry.

Well now you get to laugh at my cooling autism again! Yay!

 

The far more elegant CoolJag mk.2!

 

Fabrication complete:

Fitting complete:

It fits around all the components, so I don't have to file any little slots for it to fit over things:

I made it for good positive airflow, but it's also baggy enough for convection cooling to occur if the fan fails and I don't notice:

Not strictly necessary, but Tom and Jerry do tend to get a bit hot.

I clocked them with my infrared thermometer at around 65c, which is plenty warm.

Since I fitted the cooler, they tend to sit around 28c.

 

A cool jag is a happy jag! :)

Yeah, I remember the original CoolJag :)

 

This is a very nice job, and the fan is quiet indeed, but..... why do you "scratch" your Jag? :-D

Thanks man :)
It took me ages for such a small thing.

Haha. Yeah I wanted to make a little noise to show how quiet the fan was.
Hence the scratching.

I was going to ask if beating was an issue with the jag. I never really thought about it, but that's a pretty nice little can mount. Is it 3d printed?

Can you fit the top casing on after the mod?  The JagCD could really use some cooling IMO, those regulators get toasty!

Heat isn't really an issue as such.
Tom and Jerry get hot, but not too hot.
That said; no silicon ever complained about being cool :)

It's not 3D printed. I made it the hard way.
Cutting and bending and filing.

Yeah I made sure the RF shield and lid can fit properly. That's why the fan is sunk into the duct instead of being on top.

I wouldn't worry about the regulators on the CD unit.
Most regulators of the period had a maximum operating temperature of like 180c, but never get anywhere near that hot. :)

It was a common issue when people got home from the game store and then plugged in titles such as Checkered Flag and Supercross 3D after paying good money for them.
