Feel the need to add a cool mod to your case but are slow on ideas? We are checking out a quality digital thermal display that tracks 9 read-outs! Let’s take a look at the product, and see if it can stack up with our high expectations!

Page 1 – Introduction

On the chopping block today is a product from Logisys Computer. Logisys was kind enough to send up this digital Thermal Controller for reviewing so that’s exactly what I intend to do. This piece is meant to be installed into a vacant 3.5 bay which we all should have, because floppies are all but irrelevant 99% of the time.

You do have an open floppy drive don’t you? There are a lot of these types of products offered out there so I am going to see how this piece of hardware stacks up to my demanding expectations.


  • Monitor CPU, SYS-r (rear), SYS-f (front) temperatures
  • Monitor the speed and operation of up to 3 fans
  • Temperature reading selective in Celsius or Fahrenheit
  • Input voltage: DC 12V from power supply with a Molex 4 pin connector
  • Alarm for an overheating system or fan failure
  • Compatible for all cases with an open 3.5″ bay
  • Peaceful and subtle blue display
  • Retail $20.99

This appears to be a nice little piece of hardware that, in all honesty, might prove to be rather useful as a hardware monitor. Let’s get into the design and functionality of this product.

This is designed, as stated before, to occupy an open 3.5″ drive bay, so that’s exactly where I will put this. As it stands, I have two 3.5″ bays in my black Antec SOHO case. The top one is occupied by a 100MB Iomega Zip drive. By process of elimination, the Logisys is going to go right below it. In this case, I am fortunate enough to have removable drive bays which will make this install easy.

Upon removing the drive bay, I quickly installed the Thermal Controller, which will reside directly below my Zip Drive. The controller is held firmly into the bay with 2 screws. This struck me as odd that only 2 mounting holes were available because without the Zip drive above it, the Thermal Controller might be prone to wobbling up and down if not firmly in the case’s front bezel. Aside from that, installing the Thermal Controller in my case was easy and painless.

Physically getting the Thermal Controller into the drive bay, then into the case was simple and hassle free. Hooking up and routing the cables is another thing and could prove difficult. When I say difficult, I don’t mean that it’s going to take an engineering degree to install, but that it is going to be a tedious endeavor if you take any pride in the appearance of your computer.

There are in total, 7 connectors coming out of the back of the Thermal Controller. These include a hard drive connector that plugs into your motherboard, three 3-pin connectors to monitor your fan speed and 3 thermal probes to place on or near your CPU, the front of your case and of course, the rear of your case.

In all honesty, you can place the probes anywhere in your case such as your hard drive, your chipset, your power components on your motherboard.. the options are limitless. Managing all of this can be a nightmare for most but for the sake of this review, and to not compromise of the integrity of the readings, I did not route all of these wires in an optimal path because that my friends is for another review.
