4.0 out of 5 stars Poor Cooling Design, Fixed
Reviewed in the United States on February 22, 2019
After going through all the reviews people have left about leaving the front door off or drilling holes in the front door to allow proper cool air to enter the case... I broke out the soldering iron and Dremel tool.
Users here and on Mediasonic's forums note that the fan is noisy. Being that it's a rare 80mm x 20mm fan from an obscure company I chocked it up to a poor fan being used and ordered two replacements. One an 80mm x 20mm Evercool and an 80mm x 25mm Noctua. Both were 3pin fans.
I won't go into the gory details but after ripping out the 3rd wire, the yellow one from each of these fans and soldering the 2pin connector onto the fans positive and negative wires I found that also, Mediasonic reverses polarity in the fan connector mounted on the PCB. Annoying. What is normally a positive lead is a negative lead and vice versa.
Plugging in the Evercool fan and running the unit on auto fan mode at the lowest level was better than the stock fan but there was a ticking noise I'd not heard before. Plugging in the Noctua fan I also heard a faint clicking noise the became more rapid the faster the fan spun. Odd...
So I plugged in a 3pin fan controller with a variable 8-12v potentiometer on it into the two pin fan header on the PCB after some more soldering. Still, there was a very odd clicking noise coming from any fan hooked up this way.
Whatever method the unit is using to modulate fan speed via voltage reduction is... not clean.
My unit is going into a media center that is open and any noise above small air movement will be easily audible. I wasn't about to tolerate the level of noise this case was putting out.
Enter a 12v PWM temperature based fan controller, a Noctua 92mm PWM fan, my 3D printer, dynamat, epoxy, more soldering and some hot glue.
I'll save the gory details. Suffice to say I created a plate to mount around the 92mm fan that would epoxy inside the back of the unit. Cut out a hole in the back of the unit for the fan to fit through, epoxied things down, soldered the PWM fan controller to the positive and negative leads coming directly off the power supply jack on the PCB, roughly cut out as much plastic as I could on the underside of the front of the case and hooked things up. Oh I also cut a massive hole in the top of the drive cage because there was sheet steel entirely covering the area just above Drive 1 where heat would collect. There's now a good 20-30mm of space above Drive 1 where the heat can now rise into and be pulled out instead of cooking Drive 1.

Silence!!! Except that the HDDs are now far louder than the fan noise. That's acceptable but I may line the interior of the case with dynamat in a few days.
Suffice to say I went to lengths to make this thing quiet and cool. It is very poorly designed from the factory in this respect. I have no doubt it's contributing to people's drives failing.

Another irk I have with this case is that it does not suspend the drives. I had another double HDD dock that responded to Win10 telling the drives to spin down when not in use after 15 minutes. The Mediasonic unit does not allow the drives to spin down. THIS IS BAD. Because I'm using 5400rpm drives it's less of a concern but anyone doing a lot of file transfers with 7200rpm drives will see a lot more heat.

I have no idea about the longevity of the unit as it's only been in use for two weeks but I would hope that more/cooler air flowing through the case will help it live a long life.
Mediasonic could have done a far, far better job and charged maybe $20 more for this thing.
I don't mind voiding the hell out of my warranty on a product this inexpensive but what I do worry about are the people who've had drives corrupted by this thing. I've bought an external USB HDD to do periodic backups just in case.
