Whrrrrrrrr. Buzzzzzzzzzzzzz. Whiiiiiiinnnnnnnne…
Guess what? It’s a noisy CPU fan on a stock CPU heat sink. Can we do better?
Is an improvement available that results in lower CPU temperatures and near-silence fan performance?
One CPU cooler that I am impressed with is the Cooler Master Hyper 212 EVO. Whenever I build or upgrade a Linux system, I usually purchase one of these little marvels because it works reliably well with almost no noise.
I upgraded the stock AMD CPU cooler on a Linux system using an APU in an FM2 socket because it was too noisy and inefficient. What did I replace it with? Why, the Hyper 212 EVO, of course!
Here are some pictures…

Can you type faster than a robot?
The Ubuntu Linux repository is filled with lesser-known gems that are surprisingly useful and fun. Speedpad is one of them.
This a typing practice program that displays a random quote from fortune, but you compete against a typing robot.

“Does VeraCrypt slow down reads and writes?”
Do you want to encrypt your data, but are you concerned about a performance drop?
I was curious to find out if using VeraCrypt resulted in slower reads and writes for whole disk encryption with an external USB drive and for a standard file container, so I performed my own tests in Linux Mint 18.1.
How would the different encryption algorithms affect performance? Are some faster or slower than others?
Here are my results…

Linux kernel 4.10.0 (stable version) was released a few days ago while VirtualBox 5.1.14 was released about a month ago. I have been using both, and they have been performing well.
Kernel 4.10.0 touts improved NVIDIA graphics support, but my experience was lackluster with SLI. On the other hand, 4.10.0 runs great with existing Linux systems using non-SLI graphics.

“Can I use RapidDisk with VeraCrypt?”
Absolutely. If you have an encrypted volume with VeraCrypt, you can easily add a RAM cache to improve read performance.
The setup is the same as with a regular RapidDisk cache but with an added extra step to map the VeraCrypt volume.
