No guarantee that nvidia will even release a HDCP 7600GS (or any other current model for that matter).

The zinc goes somewhere - it becomes zinc oxide and yes it'll get deposited all over everything.

Got a U2-UFO on the way to me, decided I wanted something chunky to hold all my watercooling gear. ;) Not sure on the quietness front, it's a pretty open case which tends to mean noise gets out, but with quiet fans and such you could keep it fairly quiet I think. HDD noise is likely to be an issue -...

Noticed my Atlas 15K II was getting a bit warm last night (I recently moved it from the main drive cage to being suspended in the 5.25" bays). Putting a spare 80mm fan blowing over it seems to have massively reduced the temps and the fan is inaudible over the rest of my stuff (it's a yate loon fan a...

You massively shorten the life of the drive by running it hot. If *any* piece of the drive is even close to 70C it's way too hot.

Main problem is likely to be reduction of flow from adding extra blocks. That will have far more impact than any additional heat load introduced.

Also 70C is too hot for a HDD - most are only specced to 60C operating temp...

In most cases TEC systems are going to be hot and noisy. If you're careful they're hot and quiet. But TECs dump a lot of heat into the loop regardless of how you use them, and cost a lot of run (think roughly tripling your comp running costs and you're in the right ballpark).

Using the fan headers could be a good idea, maybe even for other things than fans, because I can easily turn it off with SpeedFan. It should work as long as I'm not connecting too power hungry devices. Can I connect a resistor to a fan header? Trying to regulate a resistor with PWM sounds strange, ...

More discussion on the "quality" of the noise would have been nice. Something with a broadband hum is generally less annoying than a high pitched whine regardless of the actual volume. ;)

First, what kind of metal is this? It's really heavy, and shiny. It might be chromed steel, I'm not sure. I don't want to add any kind of corrosion catalyst to my setup. As of right now it's all copper. Probably nickel plated brass. Reducing to 3/8" will cut flow quite a bit, you might want to just...

It could be the fan bearings warming up and developing less fricton. However, at 1900 RPM you're transitioning every 15ms, which is a bit close to the frequency you're checking. It could be that the actual variation is quite small but you're getting odd effects because the frequency you're sampling ...

If you can't switch it off in the bios you have basically two options: 1. Run a fan off the header. 2. Pretend you're running a fan off the header.
