Corsair QL140 RGB vs Phanteks T30-120

In the preservation of self care, I gotta say that while I am visually happy with my purchases (Fans and controller) and happy with their performance, I am wholly dissatisfied in Corsair for not making their fan kits and all in one type of deal. Aside from that, the fans are also fairly noisy, even at low speeds, and the balanced setting within the iCUE software has the speeds bouncing around like crazy when I am not even doing heavy workloads, or gaming. But they're so pretty, so that doesn't matter, right? RIGHT? And then, there's the final insult. Amazon has such a low quantity of these fan kits and single fans, that you are only allowed to purchase ONE OF EACH per account

We were quite surprised by the results, especially in the radiator airflow testing, where the T3120 left both competitors behind by a healthy gap. Whe...

Which means you HAVE to use the iCUE software to make them work with your other stuff. Don't get these if you want everything to sync up with them unless you have ASUS Aura Sync compatible items and are willing to use additional software (like Jacknet RGB) to get it working together (not without some issues, but it's something at least). However, if you can work within those limitations, these are the BEST looking RGB fans I've seen yet, even nicer than Thermaltake's Riing Trio/Quad fans. Had to take one star off of the review because of the custom ecosystem and all of the additional splitters and adapters needed to use them, and due to the custom ecosystem they force you into, but they are a quality product

Short recommendation: This is probably the best fan on the market right now (as of 2021-09). Be sure to measure the available space in your chassis (or beside your radiator) to ensure the extra depth of a 30 mm thick fan won't be an issue, and buy this fan if it will fit. Unless noise levels are absolutely critical for your work, nothing else seems to beat the T30-120's versatility at the moment, and the fan would likely do well regardless of whether you need better performance (at higher noise) or better acoustics (lower volume) with still decent performance. Review: The T30-120 is a 120x120x30 mm fan, which is 5 mm thicker than your average 120 mm fan (at 120x120x25 mm)
