Review: Whisper-Silent Cooling for a Hot-Headed Xeon - If you’re looking for a cooler that actually tames Xeons without sounding like a jet engine, this is it. My Dell Precision T5820’s stock cooler had my W-2135 cooking itself at 90c under full load, but this Noctua dropped it to under 70c with barely a whisper. It looks fantastic inside the case, fits perfectly, and feels like it’s built to last. Installation takes a bit of patience, but once it’s on, you’re set. What was good: The build quality is classic Noctua, with materials that feel premium and fans that are as quiet as promised. Performance-wise, it’s night and day compared to the stock cooler. Idle temps hover around 35c, and even at full tilt the CPU stays comfortably under 70c. The cooler looks surprisingly nice too, especially paired with the green PCB in the Dell chassis. One of the best parts is that it’s one of the only third-party coolers that actually fits the Precision T5820 without clearance issues, which makes it a rare gem for this system. What wasn’t: Installation was a bit fiddly, and it took me a couple of tries to line up the screws just right. It’s not the kind of thing you’d want to do often, but thankfully you only ever need to install it once. The only other nitpick is cable management, getting the fan cable routed so it both looks neat and avoids the fan blades takes some trial and error. Beyond that, no complaints. Recap: This cooler is exactly what I needed for a workstation that runs hot but needs to stay quiet. It’s solid, silent, and effective. If you have a Dell Precision T5820 or another Square ILM socket system and want to upgrade from the stock cooler, this one’s a no-brainer.
Review: Superbly Designed and Quiet Cooler! - I'd normally for liquid cooling in a server build, but this was a unique situation where I had an older Supermicro motherboard with dual E5-2698v3 Xeons (LGA 2011-3) in a small (non-server) case, and I needed something that would keep it cool but not sound like a jet engine. Installation was flawless. Swapping in the narrow ILM guides was a breeze. The included hex tool for locking down the standoffs even has an indentation to allow tightening from an angle. I'm amazed at how quiet these four fans (two per cooler) are and how well they cool in the same case. It's at the high end of what one would pay for a non-liquid cooler, but this is worth every penny.

### ⭐⭐⭐⭐⭐ Great Ventilation mod!

Perfect fit in my Dell Precision 5820! Great fan mod for better ventilation and CPU cooling. I also added 2 additional fans on the back of the case for better heat removal.
