Replacement Dreamcast Thermal Pads!

Post#1 » Sat May 19, 2018 3:41 pm

Dreamcasts are almost 20 years old now and its overdue to replace the thermal pads. Surprised the dc pads lasted this long.

Here are some decent replacements..

https://www.newegg.com/Product/Product. ... 6835186166

1.0mm Minimum- 1.5mm Recommended!
Cut to fit they come in a 50mm sheet or 145mm if you take your dc apart often I recommend getting the large sheet for extras.
Caution: Some pads are quite fragile like clay and can come apart especially if reused so be gentle.

(If these are unavailable to you I'm sure any other thermal pads that thick will do fine)

I have been using these pads for a few months and they seem to do a great job.

Don't forget to replace the Bottom pads underneath the motherboard too, they protect crucial components that are directly under the cpu and gpu they are very important. There is also a thermal pad in the gd rom drive you can try to replace that too.

Was going to post some pics but they're too big to upload? sol dc talk..

Keep your Dreamcasts cool and last forever!

Why hasn't there been any responses to your topic?

It's actually something very important. I recently did a thermal pad-swap because of your topic. You encouraged me to make it. ;)

I did however a modification to your Thermal Mod. I used the thermal pads from your post (1,5mm thick as you recommended) but only on the bottom side of the motherboard. On the CPU / GPU I used a "24 carat diamond thermal compound" paste on both. After changing those goo-things they used on the Dreamcast, I noticed that the bottom got a lot hotter of the console (which is good since this means the heat comes out instead of keeping it in the console)

So I got rid of the "Laser in console, don't look inside the laser"-bla sticker to get more of the ventilation holes open (I think this is only on the PAL consoles...?)

Then I swapped the little plastic feet of the dreamcast with those: https://www.amazon.de/gp/product/B00AJI ... UTF8&psc=1

So the Dreamcast has a wider opening on the bottom. Since I use the USB GDROM and I don't have the DreamPSU (yet, but it's preordered) my Dreamcast tends to be a lot hotter. So I *also* did the 300ohm resistor mod. Since then (your mod, my rubber feet idea) the Dreamcast is stone cold. And works like a charm. So if anyone thinks of changing the thermal pads - do it, you won't regret it. Technology has advanced in the past 20 years and those thermal pads / paste do magic to your consoles ;)

Great topic. I will look into this soon.

An idea would be to compile a master document for Dreamcast Maintenance and modifications. Maybe in a Word document and add to it as more things are discovered.
Dreamcast: Blue Swirl, 60hz, White LED, Removable battery holder, Internal SD card reader, BBA, DreamPi, RGB Scart
