Keep hoping GamersNexus will do a follow up on the 140. Steve reported in the cooler round up they removed the cooler from their roundup due to QC issues.

Just about 6 mins in if timestamp doesn't work for you.

One of the best CPU coolers you can get for under $100.
Probably not your issue, but I want to add that my dad built a system with a larger cooler a couple years ago. He installed the heatsink the wrong way around, pushing it down toward the expansion slots. When I was visiting, I corrected it, and moved his videocard to the full x16 slot.

I'm not sure if the PA140 has an offset, but the 120 did. People should make sure they install large coolers correctly.

Price on this is fine, YMMV on sizing. This thing is large enough that it conflicted with the video card on a cheap build I was doing for a friend. Ended up going cheap AIO instead.

The price has crept up on these a bit over the last year or two, but still a no-brainer for an air cooler unless space is an issue. I've got two of these one regular and one SE that have been perfect for almost two years.

You can get the SE version, which performs identically in my experience, for $34.90 right now too.

For the price this is an excellent cooler, but it is HUGE . On my AM4 ROG motherboard with the Corsair RGB RAM there is a conflict with the front fan and the RAM's height. I was able to mount the front fan slightly higher to allow the cooler to fit.

Other than having to mount that front fan higher, it has been an outstanding cooler. Temps are somehow better regulated than they were with my prior Corsair H100i water cooler that failed when we moved. Also this cooler is much quieter too.

The phantom spirit 120 se is $35 and is ever so slightly cooler and not as bulky.

Not gonna lie I bought this as a replacement for a computer I was repairing for someone and when I was running a cpu stress test to make sure thermals were ok the back plate broke right where the screw attaches to for both top holes and the cooler was hanging off. Thinking I over tightened it, I got a replacement and the same thing happened to that one. Reading some reviews I wasn't the only one this happened to. It's plastic.

I have the PA120 SE white ARGB. It's similar price. It's been stellar for my 5700x3d. I'm sure the 140 is better. But obviously bigger.

There's other 120 versions for 35 ish always available and great options

Of the 120. This post is for the 140 though.

FYI, this is the newer 140 model. It only came out a few months ago - you have the old smaller 120mm size, which was indeed cheaper.

In either case, not "better" enough to upgrade to. Once one gets to "extremely large cooler" (whether heatpipes or an AIO), the minuscule differences don't actually matter. We're not talking 20C drops here from decades ago, unless someone wants to run fanless with external radiators.

Can only speak to the legacy 120, but its an absolutely fantastic air cooler. I'm probably living the overkill life by using it with my R7 5700X3D but whateva.

Worth nothing that I'm only using one fan in the middle instead of both, still keeping my CPU temps crazy low while keeping the noise down.

140 has the offset too
Oops, my Frost Spirit 140 has it, not sure about the PA model
