I recently bought a Bluetooth dongle for my wireless keyboard. After lots of measurements, I ended up fixing it to ceiling for optimal signal quality. There was a problem though; the LED. The pulsating blue LED was just too much for me. Or judge yourself, imagine this:
pulsating wildly every night on the ceiling. Not my thing. I could not find anything with google about disabling programmatically the LED, so I went the hard way and removed the entire LED from the dongle myself with soldering iron.

In my previous blog post I described how I fixed my Asus Strix GTX 970 DirectCU II OC graphics card by changing fans and thermal paste. I noticed 7% increase in measured performance. What I left out from the post that I also discovered and observed other methods for increasing the GPU performance.
Fallout 4 came out on year 2015. Before this, a realization came out, being that my old rig could not handle the new game in its current state. What a bummer. But there was a silver lining. Or bronze. Or at least iron, I swear.
A Finnish computer shop had a bundle campaign: Asus Strix GTX 970 DirectCU II OC graphics card + Samsung 850 EVO 250GB for 399 EUR. I considered this a deal and bought the bundle. I think they might have had free game voucher also in the mix, but Google evades me on this.
The GPU arrived and it had many problems, it seemed. First there were instability problems with strange block garbage. These cleared after I ditched my “high-quality” Intel DZ77GA-70K motherboard for Asrock Z77 Extreme4.
One issue was still present, being absolutely horrible fan noise. This had been present from the start. Seriously. You buy the thing, take it out of the box, run some stress on it, and the whole thing rattles like it is going to give out functional smoke any minute.
The thing is, that I was able to fix it. There is video about the results here, check it out first. Then we show you how we did it.
