Power supply EXPLOSION
Ok, maybe watercooling the power supply was not a good idea.
It certainly kept the power transistors with the big heatsinks cool, but what of the poor little diodes and a transformer, which didn't get the airflow they expected? Been working fine for a few weeks, then suddenly..... about 15 bangs, flashes, sparks etc flew out of it, as though I had lit an entire box of fireworks under the desk. Strangely the PC continued to run while this happened (for about 10 seconds, at which point the PSU gave up and it went off. Fuses all intact! Replaced the PSU, and the PC booted ok! Just one drive of the mirror/stripe appeared to be blank/corrupted, but it's autorebuilding it in the background. http://80.229.155.158/temp/psufail -- *****TWO BABY CONURES***** 15 parrots and increasing http://www.petersparrots.com 93 silly video clips http://www.insanevideoclips.com 1259 digital photos http://www.petersphotos.com Served from a pentawatercooled dual silent Athlon 2.8 with terrabyte raid Polynesia -- memory loss in parrots. |

WaterCooling keeps the CPU and what ever else it's connected to cool..
So you dont have 45/50c air feeing the bottom of the heatsink.. That means that the PSU shouldnt have required tons of airflow.. It looks to me like the psu just fail'd (short in transformer).. Case Circulation is good to have anyhow when you have a few harddrives in the system.. "Peter Hucker" wrote in message newspsbhnptolaiowgp@blue...

That's one hell of a failure. I thought I was maybe overloading it, but I'm using 200W peak, and it was a 300W supply.
Anyway I've sourced a fanless one for £120.... On Wed, 21 Jul 2004 14:32:50 GMT, rstlne wrote: WaterCooling keeps the CPU and what ever else it's connected to cool..

Tho to be honest I woulda probably been more tempted to just mount a couple of NB coolers on the heatsinks inside the PSU itself (sure it could be done). |

But I think more than that needed cooling. Ahhhh yea I see what you did now ... Yea you probably needed a verry small airflow.. But nearly all of the heat comes from those 5/6 (or 8/9 on some) amps that are connected to the 2 (sometimes 3) sinks.. I find it verry strange myself, Are you sure that there wasnt any leaking or that even there wasnt possilbly metal shavings inside the unit after installing the blocks? |

But I think more than that needed cooling. Yes, the best solution would've been to simply leave the power supply alone and install a lower flow fan, with rear grill removed, then mod the REST of the system case to provide positive pressurization that forces more air though the power supply. Your conclusion was correct that there's more to cooling a power supply than just keeping the regulators cool. |

Tho to be honest I woulda probably been more tempted to just mount a couple of NB coolers on the heatsinks inside the PSU itself (sure it could be done). Nope, there are ZERO nice new fanless ones. The highest quality, best specs and longest lasting PSU are all actively cooled. Effective passive cooling for a modern system will require such large passive 'sinks that it won't come near fitting into a PS/2 size allocation per the PSU casing or system chassis. Best attempt is when huge fins stick out the back of system, but even then there is no chance PSU will last as long unless quite specifically made with different spec and type components inside, which none have been due to greater cost. |
