Thought I'd jump in this thread, as I'm waiting on a 3900X to arrive, and also ordered (after a couple days of considering specs/performance/price) the TS140P, along with a couple TY-143 fans. I'd considered the Macho RT and Noctua D15 as well, but prefer having more space. I'd been in the land of water-cooling for the past 9 years, lack the time to maintain it now, and am finally upgrading from a 2700K that's been under water and overclocked for a while. That returned me to air-cooling. I'd been using a Hyper 212 LED with 2x Vardar F4-120ER fans to cool a 2700X for the wife, and during Intel Burn Test, and stock speeds/voltages, it was hitting 66C and not going any higher. The fans are quite similar to the Gentle Typhoon fans, and run 2200 RPM. I find that they not only pushed through radiators better than standard case fans, but also seemed to do well with the Hyper, so I'll see how they perform compared to the stock fan, and TY-143 pair.
The mounting design from Thermalright doesn't exactly thrill me, but if it's solid, then I have no complaints. It's going in a "Cooler Masher" HAF XB Evo, which supposedly has enough room, though I've not read entirely through this thread to see if anyone else has confirmed the fit. The case fans are already those same EK Vardars, as they sound good to my ear, and move a reasonable amount of air.
It's kind of a homecoming, as I used an SLK-900 topped with a 92mm Vantec Tornado on an Athlon 2500+M back in the day, and saw that chip hit somewhere in the 2.6 Ghz range. I miss that heatsink, though it did sound something like a hair dryer.
Thanks to everyone who's been working with these heatsinks and posting info!
