Hi guys, is the competiong still open? coz if so i have a cool DC mod coming along, I have only had my DC for 3 months and am suffering overheating probs, mainly coz the fan is dying, so i pulled my DC apart and didn't like the design, so i am now adding a mega cool heat sink which sheet reaches till outside (maybe i make 2 too) and outside i will have a CPU heat sink grill with fan.
Currenly I have just cut the aluminium heat sink sheet to size soon i'll post the description + many pics either on my http://www.tech4000.cjb.net site, or on [url]http://www.segaracers,cjb.net[/url]
See you around ppl
Cool heat sink/fan mod

Her eit is, not finalised yet, need to use a better grease, then fully close it and tighten it with the screws, and also add another grill+heatsink, but it is looking good!

Those are the only pics i'll post for now, but more will soon follow.
But that is the only pic i am allowing to leak.

I have to say...
I dont understand what that is supposed to do. The processor and gpu are both near the center of the dreamcast. I dont see how adding a heatsink to the back is going to help any. Even if it is attached to the metal shield covering the mainboard or even if its connected to the metal directly touching (through thermal pads) the processor and gpu... it seems like it'd be too far for it to make a differance.

For your convinience to understand how it is attached i added 2 other pics man.

First of all the metal is designed for heatink purposes, and while the original DC heat sink is designed in such a way that the heat remains inside and that fan has to remove it.
The heat sink I made (which is still not fully finish, still got to add a CPU heat sink) makes dispurt the heat otwards, that way the h. sink is already cooled externaly.
Obviously SEGA, and other companies don't employ similar methods, because the heat sink does get warm/hot and it could be concidered as a hazzard or something, you know with all the safety standard laws that exist.
Idealy I wanted a CPU heat sink ontop of the CPU + GPU, but not enough space, so i need to extract the heat first.
I also plan to do something similar to the other side.

I once tried the exact same thing, and I can objectively tell you it worked, since games that "froze", like Sega GT, Phantasy Star and Crazy Taxi 2, worked like a charm afterwards. Also, on games that exhibited messed-up textures, (a sure sign of overheating) like Virtua Tennis, there were no more graphic glitches. I used copper piping and aluminum cooling fins ripped off a car stereo.
It's a combination of radiation/convection heat transfer, it's probably the best way still to cool electronics. It doesn't have to be precisely on top of the processor to work. It's better to radiate the heat to the outside, and heat will dissipate, rising in air.
Very crafty (and useful) mod.
