**This is just a copy-paste of my reddit post but thought you guys may like.** Not much to say about this one, found a laptop cooler fan which ran at 5v, perfect for the Dreamcast. http://imgur.com/a/lXloA I've been running the Dreamcast overclocked to 240mhz almost full time now to help with slow-down in specific games. I mapped out the location of the heatsinks and fan intake and cut the hole in the heatsink/shielding with a dremel. The fan sits perfectly between the heatsink and USB-GDROM PCB and vents out the rear grill. http://imgur.com/Esg0FGr Regarding heat the system now runs WAAAAY cooler. Before the mod and after only 30 mins of regular use the system would get quite hot on the PSU side. With the added fan the system is now barely luke-warm after an hour or so of overclocked gaming. The system is slightly louder now but still barely noticeable, if you have the tools, skills and parts to perform this mod I'd highly recommend it. Here is a link to the exact fan and shroud used: http://www.ebay.co.uk/sch/sis.html?...R&_itemId=291318133085&_trksid=p2047675.m4096 I've also created a video for those interested:
Awesome find. I searched ebay and amazon for "Dell Vostro 320 Inspiron One fan" and found a few options. Bought 2 from china
One question though.. Both fans seems to be blowing out. Would you not get even more flow of air if you reversed the standard fan so it blows into the machine? Granted, the Dreamcast has enough air holes so its probably better air gets sucked in from all over the place...
I did try that initially, thinking the same thing but the system did seem to run warmer. I'm not using any tools to measure heat and only going by touch but running the case with negative pressure (both forcing out) seems to make it run cooler for some reason. Results may vary though.
Hi, I just signed up here, wanted to give my thoughts on this mod. I like the blower fan, fits the system pretty well. Would this work with a system that still has the stock GD-ROM drive? Are you going by how outgoing air temperature feels on your hand or are you feeling the heatsink shield directly? Warmer air coming out would mean better heat extraction IMO. I would get a heat probe or one of those non contact thermometer guns and check on the metal after an equal amount of play time just to be sure.
Welcome Wingmantis. It should still fit with a standard GD-ROM drive as the PCB would be about the same thickness. I haven't used any heat probes or IR guns to check temps and have only ever gone by hand. I will say however that it was never designed to cool the GPU/CPU on my system as I've never had temperature issues with them. I designed it to help with overall case cooling as the PSU gets far hotter than anything else in there and it seems to have done the trick.
just wanted to say Nice work and I plan to fallow in your footsteps. my only question has nothing to do with the fan. Did you remove the 12v rail and did that also help with heat issues?
