Water Cooling Computer Radiator, 12 Pipe Aluminum Heat Exchanger Liquid Cooling Radiator Heat Sink 120mm for CPU PC Laser Water Cool System DC12V Black with Tube

Great functionality, perfect size, went right in the spot I had planned for it on the front of my case over a fan, no leaks whatsoever, build quality is great, painted in a nice satin black goes with the rest of my interior of my computer.

As described

I used it for cooling another type of water cooled machine. It works well. I wish the fans were 120V instead of 12VDC.

First impressions (WOW!) a phenomenal product, in all respects. It has a very solid feel, fit and finish. A bargain and perfect for modeling a few concepts from scratch. My principle concern is low level fan noise, detracting from musical experience... it takes you out of the moment. We will see. *Not faulting DIY hz, more in that possible complexity could prove "conventional" heatsinks. I chose and "all aluminum" water system, heat block and heat exchange, to minimize reactive nature of (all parts in the) system. As a high power (audio/musical) A/B amplifier, heat dissipation, adequate heat sinking is required and/or could prove a penalty, in size, end product layout... falls around power transformer and heatsink. My thinking, thus the proof of concept supporting my personal designs... I can have "enough" dissipation for bias and maximum drive, for power listening (think 350-500wpc @8ohm) and have "enough" for the musical peaks. A robust 10 x 12 x 1.25 heatsink gets really hot, not dangerous... a problem with large heatsinks is uneven cooling / dissipation in the output stage possibly lending to low level non-linearities. typically the bottom portions of the heatsink are (convectively) cooler than the top. Place one (mono) amp nearer to an AC vent, a sun filled window or drafty room/basement, like mine ... it is common up to 10 degrees difference, channel to channel relative to placement, with large heatsinks, doin their job... I am excite to think WAY outside of the box, will update as project evolves, likely building one cooling chassis / tower for 2 mono amps, with several more garden hoses in the back ground, and not as a figure of speech.

So far, I just don't know. Fan seems fine, spins freely by hand. Radiator is good, construction seems good and nice welds for the nipples for incoming and outgoing water flow.. Back to the fan, the fan does not power up using the red/black leads. It has continuity, just don't know. I will write some code to a microcontroller to see if that makes it hum. More to come, I'll update in a couple of weeks or so.
