WC'n Corporate systems... - Page 4

I know I will probably get pounded by everyone here for this but anyway here goes. Why not use the Coolit system. These machines are not OC'd and they are dual cores, so it may work fantastic in this situation. You could probably get a good deal butin in bulk and even at retail they are like $150.

may need an adapter to fit 771, not sure, but worth a look.

If the large fan to the left of the CPUs is the main source of the noise, perhaps you could mod it to run off of the +5V line on a Molex connector and undervolt it. Try the mod and monitor the temps, if they're within reasonable levels this would be a very easy and cost-effective solution to the noise problem.

You might wanna check your math Manyak.

200 times 20K = $4 million.

I thought of that too.....the bios recognizes the fan isn't spinning fast enough thus ramping up the other system fans to compensate and I'm back in the same boat of an obnoxiously loud system.

To counter act that I decided to split the yellow cable from one of the 120mm fans and connect that to the mobo connection for the 150 and it ran quietly for a bit but once temps climbed it still spun the rest of the fans up to hurricane proportions.

What it comes down to is an un-adjustable bios that tries to keep temps low utilizing loud fans and inadequate passive heatsinks.

I just ordered some Dynatron H6EG's to upgrade this system to active heatsinks and keep the air flow from left to right. Hopefully they'll keep temps low enough to stop the bios from spinning up the fans.

Ouch Manyak....I'm not a wc'n n00b, and understand that I would also be putting together a preventative maintenance schedule for the systems if it came to water.

lol I didn't mean it that way, I was just saying that the other guy (Dirtyduck) seemed a bit too gung-ho about it.

By the way, if you wanna mess around with the fan voltages there's a little trick. I had to do this on a Dell desktop when I replaced its 3000RPM fan that gave out. Just connect the yellow wire from more than one fan onto the motherboard sensor. You can even hook up each fan to more than one sensor if you have to. This way, the tachometer pulse ends up going at the rate of Fan1+Fan2. The motherboard will THINK that they are all running at high speed, but they can be set to anything you want and powered from wherever you want.

It's cool, I know you were just being cautious.

Hooking the fans up to a seperate power source and splicing the yellow wires is my "plan B" if the bios still wants to crank up the fans after "plan A" (active heatsinks). I'll do A+B before I go C (water), that is unless the bossman says do it anyway. We'll see.

Did you remove the unnecessary fan grills yet?

In addition to what everyone else has said, what kind of TIM are they using and is it just gooped on or applied properly? How good of contact does the current heatsink make with the proc?
