| MDD heatsink upgrade | |
| Posted by: herd on 2022-07-06 10:05:31 Does anyone know of a good heatsink upgrade for the MDD? This is the last one I did:  Its base is wide enough for both CPUs and it runs quiet and cool with the large area and heatpipes. However it encroaches on the RAM area and hard drive area. I was able to keep 2GB with different RAM modules and the small SSD still fits. It would be nice to find a good heatsink that fits better though. Anyone? | |
| Posted by: MBongo on 2022-07-06 19:56:59 I believe that the “stock” Apple copper heatsinks from the 1.42 GHz MDD FW800 are the best… but I have a loose pair of the “finned” stainless steel MDD heatsinks AND a solid aluminum one if you’d be interested in either of those two types. But as far as any ”aftermarket” heatsinks… sorry, I haven’t a clue. | |

This is the last one I did:Thus far, the best heatsink for MDD macs is to take a copper one from a 1.42GHz or higher MDD and use that in a lower clock speed one if you're overclocking (which I did improperly, killing my MDD) | |
| Posted by: Juror22 on 2022-07-09 07:44:25 I'm really not sure if this is better... or worse, vis-a-vis fitment - it comes from back in time... http://web.archive.org/web/20180829195847/http://www.aqua-mac.com/naturallyasperat.html | |

| Posted by: trag on 2022-07-09 19:19:55 Back in the Core2Duo days I explored heat sinks that had a wide enough base to cover both CPUs and were short enough to fit in the space. I don't have the resulting spreadsheet on this computer, otherwise I'd just post it. I bought several of them to test, but never did. I don't think the data would be very useful now because all those heat sinks are off the market now, pretty much. Things like the Thermalright XP-120. I was planning to build an adapter plate to use LGA-775 compatible heat sinks, but the XP-120 needs an adapter to be LGA-775 compatible. https://silentpcreview.com/thermalright-xp-120-1st-120mm-fan-cpu-heatsink/ Interestingly, still available here: http://www.xoxide.com/thermalright-xp-120-cpu-cooler.html This just happens to be the only one I can remember without the spreadsheet. I think there was a flavor of Samurai (Scythe Ninja?) that was in the right size range, but I can't remember who makes the Samurai heat sinks and it was one specific model to get the large base. I haven't checked the dimensions on this specific one, but sinks shaped like this one were interesting: http://www.xoxide.com/scythe-bigshuriken2-cpucooler.html  I think that XP-120 came in a copper version. Something like an XP-120C or some such. But I had a bunch of notes on these heat sinks. IIRC, some of them needed teh fan moved from top to bottom. Otherwise they were too high. Anyway, as with so many concepts in the legacy Mac space, I had an idea, did some research, bought some stuff, but never followed through... | |

| Posted by: CC_333 on 2022-07-10 21:35:28 That Xoxide.com looks very "Web 1.0" as modern sites go (a quick search through the Wayback Machine suggests the current design went live sometime between January 2015 and August 2016, so it counts as modern to me). c | |
| Posted by: trag on 2022-07-11 09:03:34 It looks like I didn't document the base dimensions. Maybe if I put it on the spreadsheet (sheet1) then the base was big enough, but it's been more than a decade since I put this together, so who knows at this point. Grrr. Forum won't accept an .xls file, so I'll have to wait until I'm at home to zip or compact it or something. Oh, I can just put it here: https://www.prismnet.com/~trag/MDD/ | |
