PQA Update: CPU Waterblock Performance Evaluation System

I know that PQA has been absent for a while... but for good reason: I've been working on putting my CPU waterblock test system back together! Below is a quick video tour of the system and here's the conversation in XS.


A quick photo of the test system...


Here's what's on that table covered in stuff:

- Omega FL-1504A-B flowmeter
- Sper Scientific 840081 manometer
- Extech EA15 data logging thermometer
- Volt-modded Asus P5K Deluxe
- Instrumented Intel E6400 (details on the process can be found in an early test run that I did with some heatsinks back in 2008 here...I've learned even more since then and have some new tricks up my sleeve)
- Iwaki RD-30 pump
- HW Labs BlackIce GTX480 radiator
- (8) Delta EFB1212HHF fans
...and some other junk you probably don't care about.

Anyway, this is going to be the first time I've released waterblock (cold plate) data to the public... I'll be whipping up my usual battery of pressure drop curves, deltaT (and, perhaps, thermal resistance) curves, as well as maybe gauging overall performance as a function of thermal resistance vs. pressure drop.

PQA Ep. 5: Water Cooling Pump & Fan Vibration Isolation Tips

In this episode, I cover a few basic water cooling pump and fan vibration isolation and noise reduction tricks.

As usual, I uploaded the videos in 720p HD, so you may want to view the videos through YouTube directly rather than here on the blog.

PQA Ep. 4: Boosting Your WiFi Signal

In this episode, I go over the construction of a simple and effective means of boosting your home network's WiFi signal.

As usual, I uploaded the videos in 720p HD, so you may want to view the videos through YouTube directly rather than here on the blog.

PQA Ep. 2: Water Cooling T-Lines & Multimeters

Woo... Episode 2!  This one's a two part episode because I ended up running long on both of the main questions.  I think it's gonna take a few more episodes before I get the hang of keeping things short (i.e. concise answers that don't veer too far off topic and don't provide an inordinate amount of somewhat related information).

I may just need to limit the number of demonstration-related questions covered in each episode...

PQA: Petra's Questions & Answers Video Series Begins!

That's right, I've finally gotten my video question and answer series off the ground... all I need now is for people to send questions to questions(at)petrastech.com so that I'll have the content necessary to keep things moving along.

Anyway, the first episode (intro & PS3 HDD swap) is below and, since I uploaded the video in 720p HD, you may want to view the video through YouTube directly rather than here on the blog.  Let me know what you guys think!
