It's been so long since I've done anything with this space that I'd been thinking about just keeping the domain and closing the web presence. But we still need the space for Lyn's site: laf-art.com ... so here we go again.

About a month ago, I had moved my PC and it's now standing in a corner beside my desk (I'm sitting next to an old chimney shaft, so there are 2 corners). The placement amplified the noise coming from the GFX and CPU fans, which had become louder over time too. On top of that I had recently put an old HDD (needed the storage) into the case(Nanoxia Deep Silence 4) with the standard mounts, having forgotten how much noise is created by the vibrations. I'd been using strips of rubber cut from a bicycle tube to suspend my HDDs in previous builds.

First order of business - suspend the HDD with some rubber. Couldn't get a hold of a cheap bicycle tube, so I used a couple of small (and cheap) bungee straps. I hadn't taken any photos then, but this weekend I moved on with the CPU fan. So here's a pic where you can see the HDD suspended on the right.

Here's the material for the CPU fan mod(minus the cable ties).

1 be quiet! Pure Wings 2 120mm PWM (available online for under €8) and a plastic bowl for 50 cents (pack of 4 for €2). The bowls are pretty common around here. I had been wanting to get a plastic funnel and cut that to size but after I got the fan and had it in my hands, it struck me that the plastic bowls of which we have several, are a good fit. Sawed of the bottom and cleaned the edges with a blade. I had previously used Shadow Wings fans for extra cooling inside larger cases.

Only 2 screws and cable ties, as the bottom of the bowl was slightly too large and I couldn't be bothered to saw off more for a perfect fit.

The CPU fan is no longer audible at my desk - even under full load.

I did some before and after measurements with HWINFO whilst running a render in Blender. CPU (2200G to be replaced and used in a build for Lyn) max. temp is down 2° Celsius from 66° to 64°. The average temp difference was higher (didn't calculate it but it was obvious from the numbers). What I did not expect is the change in the motherboard (Asus B450M-A) and graphics card(Gigabyte 750ti Black Edition) temps - down by around 4° each. I also monitored ambient temp at one of the air intakes in the front of the case.

Next thing to tackle is the graphics card. I'm thinking of turning it into a blower as opposed to open air, as that would be the cheaper option. Also simply getting replacement fans wouldn't be much fun.
