I thought so. I've got one of those temperature monitors with 2 sensors, so I can check before and after. I'm thinking I should stuff one sensor in the fins of the processor heatsink but where to put the other one?tezza wrote:Hmm. The through case fan was probably installed for a good reason but out of the three, this is probably the least critical.
I only remember all the fans running at one speed regardless of load. This pc has a motherboard of about 2001 vintage. They didn't have fans that increase speed with load at that time yet did they? That being said I've got a more modern power supply that I believe is like that but I'll have to swap out the power dongles for older type. I use a graphics card without a fan.Gibsaw wrote:It really comes down to load. If it's under almost no load then just a PSU and CPU fan.... But bear in mind that you may end up with one of the other fans running harder and being noisier than if you had just left it with two. (Does your video card have a fan? They can be really noisy if they run hard.)
You would get a benefit from installing quieter and more efficient fans like the Noctua ones. Obviously that comes down to budget.

I get that you're probably trying to improve things without unnecessary spending, but I think possibly it would be wise to re-examine your objective. If this machine is near a CNC milling machine, why does it have to be so quiet? If the noise is irritating because the CNC is idle 99% of the time, then shut it down or hibernate it 99% of the time, and extend it's service life.
If that's going to cause more nuisance than the noise, then spend some money. If this machine is running a piece of business critical equipment, what's the cost of failure?
There are all sorts of options from Noctua fans to large passive heatsinks to liquid cooling to SSD's (cooler than a hard disk) to replacing the PC itself with more modern cool-running cpu/gpu combos... If you only want to look at cooling, then target the NOISIEST fan first. Start here...

Yeah, I'm thinking about this now!Gibsaw wrote:You most certainly can. There are a number available, but it's going to come down to clearance in the case.
SpidersWeb wrote:One thing I wanted to throw in.... you can take an existing fan that's normally connected to +12 and GND, then connect it to +12 and +5 (no ground). This gives a 7V difference which slows the fan down and can reduce noise a lot when used with a motherboard that doesn't have fan control - while not completely stopping air flow.
Just an optional alternative to ripping out fans that I've used before - although usually on older stuff I prefer cool over quiet.
