Thermochill TA Series


Thermochill, a name that has been synonymous in radiator performance thanks to the long-standing PA series has released a new full line of 120mm radiators. As much as I like seeing a new line of radiators from Thermochill, I have to admit I am sad to see the retirement of the PA series. The Thermochill PA has been a long-standing favorite of mine since I first got my hands on one. However, the PA series was not without its set of quirks, although I did not mind the quirks.

The TA series looks to retain the winning aspects of the PA series, and improve or eliminate those quirks/problems many reported with the PA. The primary quirk I did not enjoy was the left over flux that required extensive flushing and rinsing, yet you were not guaranteed to have resolved the problem with flushing… the fluid in your loop after a few weeks was the true verification. We will know more on this matter as we get into testing, so we will have to table it for now.

Time to get to the nitty-gritty details and specs of the TA series, but first we have a new Thermochill family portrait for you.

Features/Specs Changes

Our norm here at Skinnee Labs is to use triple radiators as the test and comparison model; keeping with tradition, we will put our spotlight on the TA120.3. Do not fret, we plan to run thermals and pressure drop on all of them… we want the data too. For now, let us focus on the TA120.3 and dive into the specs…

The first piece that jumps out is the gigantic G3/8 barb ports have been replaced with standard G1/4 barb ports, which is one of the gripes I remember hearing quite often. Previously, you had to find G3/8 barb fittings from EK or Bitspower. But if you were the compression fitting type, adapters were in your to buy list which really were not that hard to find and over time became available at all of our favorite etailers. But this did cause quite a bit of confusion for a lot of LC’ers. However, the move to G1/4 barb ports is a good change towards the G1/4 standard across all LC components and removes the need for those pesky adapters.

From the barb ports we move down the radiator, first up is fan spacing which I am happy to report follows the 15mm spacing standard for 120mm fans. No more worries about whether your case or pre-drilled radiator mounts will work, the 24.5mm spacing is gone for good. The plenum is still there, but is slightly reduced to 9.5mm versus the 10mm found on the PA series, not much difference but a small difference nonetheless. Another design change that stands out to my eye is the folded side panels at the tanks, on the PA series these were a solid piece. This change is more than likely due to easy of manufacturing and assembly, just stood out as I was comparing the two. Also gone is the bleed screw on the end tank, which I wonder how many folks actually used the bleed screw in the first place.

Now to the core, the TA series sports eleven rows of double stacked tubes (dual row) in a 2-pass or u-flow configuration. Eleven tubes strikes me as a little odd, since you have five tubes on the left barb port and six on the right, where the PA series had twelve total (six and six) in dual row. Tubes on the TA measure in at 2.5mm in width, whereas the PA’s measured 2mm wide. The change from twelve to eleven comes in due to the copper fins rows being a bit wider, now measuring 9mm from tube edge to tube edge versus the PA 8mm fin channel. Changes in the tubes and fin channel are small, and we will have to wait until thermal testing is complete whether these changes make a difference.

Now just a short bullet list recap of the specs on the TA series before we turn you over to the photos.

There you have it, your first real look at the Thermochill TA series. Testing has begun here in the lab only a couple hours ago and this page will become the test report and review, so stay tuned!
