Thermaltake MeOrb Low Profile CPU Cooler


Product(s): Thermaltake MeOrb
Provided By: Thermaltake




The Orb family of coolers from Thermaltake has quite the variety of choices, and today we are looking at what might be considered the "Little Brother" of the Orb family, the MeOrb. Even though the MeOrb might be small in size, it still features heatpipes and offers more cooling efficiency for low profile applications.

In the past low profile coolers have sacrificed performance in exchange for smaller size, and we will try and find out if this is also true for the MeOrb.


First Impressions:

Let's take a closer look at the MeOrb:

As you can see the MeOrb features heatpipes, which should help the performance of the MeOrb. The MeOrb also features a PWM fan, so as the temps go up so will the fan speeds.

The MeOrb is pretty straight forward, and there really isn't anything out of the ordinary to point out. The accessories that come with the MeOrb are pretty standard too, and you should have everything you need to get it mounted and ready to go.

Thermaltake MeOrb CPU Cooler Testing and Installation:

Mounting of the MeOrb is pretty simple, and should really take you no more than 5-10 minutes (although it will require you to remove your motherboard). In both LGA775 and AM2 installations you'll need to remove the motherboard, however it's pretty simple for both AMD and Intel installation, and if you can't figure it out the installation manual is great and installation should be no problem.

Thanks to the easy installation there really isn't much for me to point out in this section, other than this cooler is very low and if your motherboard has cooling heatsinks close to the CPU socket you might run into some issues. With both of the motherboards we tested the MeOrb on we didn't have any issues, however if your motherboard has some extra heatsinks on it you might want to double check to make sure you'll have enough room before you order the MeOrb.

Well there we go, installation was a breeze, let's move onto the testing.



Test Setup:

We've recently re-designed our Cooler testing setup to show how new coolers are able to handle the new quad-core CPU's from both AMD and Intel, which produce more heat than traditional Dual and Single Core CPU's. We will be providing test results from both a Intel Quad Core processor (LGA775), as well as a AMD Phenom X4 CPU (AM2+) in all our reviews to give readers a better estimate of how this cooler will work on their CPU, as well as a better estimate of what the cooler being reviewed is capable of.

For Intel (LGA775) testing we will be using the Intel Quad Core Q9400 CPU, which produces 95 Watts of heat. This could be considered a mid-range processor, and while most Dual-Core processors produce ~50-80 Watts of heat, this should give you a pretty accurate estimate of what type of temperatures a cooler will provide you with. Click here to go to Intel's Processor Spec Finder website to find out how many watts of heat your Intel processor produces.

For AMD (AM2+) testing we will be using the AMD Phenom X4 Quad-Core 9950 CPU, which produces 140 Watts of heat and is currently one of the hottest running processors available. This processor should give us a very good estimate of how a cooler will perform with one of the hottest CPU's available. Click here to go to AMD's Processor Spec Finder to find out how many of watts your AMD processor is producing.

For both AMD and Intel testing, we have taken all temperatures using CoreTemp v.0.99.4. CoreTemp takes a temperature from the CPU core, and allows for much more uniform results across different motherboard and CPU platforms. These temperatures may seem higher than other temperature recordings; because chances are they are taking temperature recordings using the diode underneath the CPU, which isn't able to be as accurate, and can really fluctuate between different brands of motherboards.

For all tests we are using the Highspeed PC Top Deck Tech Station, and we are using no additional cooling in our testing. All temperatures are recorded in a controlled environment that is set to 23 degrees Celsius (73.4 Fahrenheit) to provide fair results between coolers.

For all tests we use Arctic Cooling MX-2 High-Performance Thermal Compound (Paste), We use the same thermal paste in all our testing so that we can keep our results consistent. If a cooler is shipped with thermal paste pre-applied, it will be removed and we will re-apply it with Arctic Cooling MX-2 to provide fair results.

Here comes the big test.....

The performance of the MeOrb surprised me a bit, due to the small size I was expecting the same temps as stock cooling (or even a degree or two higher), however after the dust settled the MeOrb provided a 2-3 degree performance increase over stock cooling in our testing. I was pretty impressed at how well this cooler was able to handle a Quad Core processor (our test CPU pumps out 95 degrees of heat), and this really makes the MeOrb a great choice for situations where you don't have a ton of space but still need some serious CPU processing power.

Normally this would be the section where we threw our AMD X4 Phenom 9950 processor at the cooler, however the MeOrb does not support the Phenom CPU's, so we will not be providing a comparison chart. The MeOrb does feature a AM2 bracket (so you can use it on other AMD AM2 processors) and I was curious to see how well it would handle a 140 watt processor. I found out pretty quick that the MeOrb can't handle that much heat and the temps rose pretty quickly to the point where I had to shut down to prevent damage. Thermaltake doesn't provide a specification for how many watts of heat the MeOrb can handle, but it's safe to say that is probably somewhere around 100 watts (our Intel test CPU is 95 Watts), and we know that 140 watts is just too much for this cooler.



Thermaltake MeOrb CPU Cooler Final Thoughts:

In the past when we've tested low profile coolers, I normally expect the temperatures to be around the same temps or even a little higher than stock cooling; however the MeOrb sort of surprised me in our testing with its performance. Of course the MeOrb didn't set any temperature records, but for a low profile cooler we weren't expecting it to, and in our testing we found the temps to drop 2-3 degrees in our tests, which is very good for such a small cooler. I was also impressed that the MeOrb really had no problems handling an Intel Quad Core processor, which isn't exactly a cool processor, and its ability to handle even quad cores makes the MeOrb a great choice.

The overall quality of the MeOrb is quite good (as are most coolers from Thermaltake), although just like with any cooler that features a bunch of fins you still have to be careful not to bend all the fins us (it's pretty easy if you're not being careful or paying attention).

The price of the MeOrb (MSRP $49.99) is probably a bit more than most low-profile coolers on the market right now, however if you're looking for a low profile cooler that doesn't sacrifice performance, overall it's a good deal.

At the end of the day I was very impressed with the MeOrb from Thermaltake, not only was it one of the slimmest coolers I've had on the bench, but it also doesn't sacrifice performance like so many other low profile coolers do. Even when tested on our Quad-Core test bench we saw reduced temperatures, and thanks to the super low profile of the MeOrb it becomes a great choice for situations where you don't have extra room to spare. If you're looking for a low profile cooler, you are going to want to give the Thermaltake MeOrb some serious consideration, and the MeOrb easily earned our Editor's Choice award.



  • Good Performance for a Low Profile Cooler
  • Easy Installation



  • Might interfere if heatsinks on motherboard are too close to CPU socket
