I thought of running 3DMark at the same time as running CPUBurn, but I didn't have it and since I just moved I'm wating for my ADSL to be installed - right now I'm on 56k..
Impossible do download it on 56k I kicked some Doom 3 butt instead, while running CPUBurn.
But I'm pretty pleased with my PSU temps - I'm sure I can go 10C higher without any problem whatsoever - the highest temp I recorded under load was 33C.
Since all my other fans are so loud I can't judge the loudness of the PSU fan, or if it's thermal sensor works as it should (ramp up with increasing temp). Maybe I should unplug all my other fans and test? I wish I had a PSU loader like MikeC :/
Anyway, that's not very important now. I'll get to the loudness of that fan after I've dealt with all the others
Then I'll decide whether to use a PWM control or just set the PSU fan to a static 5 or 7 volts.
I haven't cut anything in this case yet, but I'm about to - just have to decide which silencing/ducting path I will take
I visited a friend who works at a company selling stuff for ventilation/building - very handy to have a friend there
He gave me a whole bunch of ventilation tubes and adaptors to play around with.
So no I have two meters of bendable aluminium tubes, 80 and 100 mm in diameter, and 12 meters of plastic tubes (metal circles with plastic around, oftens used in kitchen ventilation) which are 82 and 102 mm in diameter. I also got some adaptors which attach at the end of the tubes - this will hopefully make attaching them to the case easy. One of them should also fit over my Zalman 7000Cu. I'll see which ones I'll be using - the aluminium tubes are good because when you bend them, they stay that way. The plastic ones are good also as they are extremely easy to work with.
With all this tubing I got an idea. At first my plan was to suspend my two hard drives in the cage behind the front fans, but now I'm thinking I'll put both drives in a vertical position right next to each other, at the side of the cage closest to the opening side panel. This would leave space in the cage for uninterrupted airflow from one of the front fans, and with a tube from there and all the way up to the RAM/NB/CPU area - voilá - fresh air directly from the outside to the hottest parts in the computer. This would then be exhausted with an exhaust duct from the CPU to the back of the case.
I think this idea could work out pretty well since the CPU/NB/RAM area won't have to deal with hot air from the graphics card - especially if I use a VGA silencer with an intake duct from the PCI back cover beneath the Silencer exhaust.
