It was a gift but I'd still buy one!

It was a gift but I'd still buy one!
I have a Dell Inspiron T3600 that I've been upgrading piece by piece since I got it. It now has the best CPU and GPU it can handle. Some day I'll spend a couple grand on a new gaming PC but for now, mine is good enough. I stream on Twitch and one of my viewers got this for me because I mentioned I'd been having trouble keeping my temps down. This paired with some new front fans and an extra exhaust fan work wonders on my current setup. I can play games like Valheim and Shatterline on max settings and my temps don't get higher than 65C. Easy to install. Had to clip the springs a little but there are tutorial videos on YT for that if you happen. To have the same computer I have. Although it was a gift, I'd definitely still pay for one. I planned to, but someone beat me to it!

5.0 out of 5 stars Fits with Dual Xeon board
Reviewed in the United States on March 6, 2023
I have a dual Xeon E5-2697V2 (LGA2011 sockets) SuperMicro X9DRi-F motherboard that has Narrow ILM mount points for a cooler/heatsink. The motherboard is inside a 4U SC846E16-R1200B SuperMicro chassis.

The original hardware had low profile heatsinks without attached fans and an air shroud. There were some really loud fans that would work well enough to push air through the server and keep the CPUs cool. I replaced all the case fans with Noctua 80mm fans to lower the noise, but they just didn't push enough air to cool the CPUs and it would overheat with enough load.

Now that I've replaced the old heat sinks (and removed the air shroud) with these coolers, the whole server stays cool (I couldn't get it to overheat with 90% CPU use) and quiet. These coolers fit in my 4U chassis with room to spare, and they came with Narrow ILM mounts that just needed to be swapped with the installed square ones. My chassis needs air to be pushed towards the back of the server, and the included brackets have ones that allow either orientation depending on your needs.
