Thank you so much for doing all this research! I got my own Precision 5820 to run a homelab and I was able to fully replicate the upgrades you made! One thing I had to do differently was reverse the orientation of the Noctua Cooler. I'm using the two PCIE ports for the NVMe flex bays and the cable interferes with putting a second fan (I was using the NF-A9 which is the same that came with my NH-D9DX i4 3U), and the rear screw posts using the Narrow ILM brackets lift a rear mounted fan up. I had to rotate my cooler 180 degrees to do the same fan orientation with flipped fan directions. Overall the noise levels dropped significantly, and you hear the silence of the 20 Db drop from the stock fans.
Fantastic video, I enjoyed getting to see the entire process of setting up the third-party fans and seeing the results of the tests you ran. You did such a great job!
What i did is i used the Y splitter for the CPU fans, and instead of attaching the 2 fans on the cpu heatsink, i attached one ( on the heatsink) and the other one to rear of the case using some bolts, works great, it never exceeds 65-70 degrees in gaming, but still it can get a little toasty at 80 degrees with a stress test, then again the cpu pulls almost 170watts so it is expected, the fix to that is with XTU limit the max wattage that can be used by the cpu and it will never exceed 75 degrees even on a stress test
You don't need 2 fans inside the case. One on CPU is enough. 1. Close your case! 2.Create flow inside by directing hot air from CPU outside (don't let it to return inside the case) 3. Let CPU fan suck the air from entire case cause GPU is doing the same so you always have enough fresh cool air in it. Noise will go down again. Use physics first then power :)
Thanks for your suggestion. I understand the importance of side cover and air pressure. The factory cooling has a shroud for CPU area to ensure high air pressure. So the side cover on or off doesn't matter. The point is not just about the final temperature. It's also about how poor is the factory cooler comparing to the 3rd-party one (although the 3rd-party one doesn't need the shroud). About the rear fan, I also tried attaching double 9.2x25mm rear fans but they doesn't make different and bring up the noise. It could be about not enough air pressure issue. So making the rear fans effectively work is something more complicated than I thought.
Great video. Only one thing I would say is if you're trying to demonstrate sound levels I would have removed the music as it gets difficult to hear what you're demonstrating.
Thanks for your comment. I apprecitate it. I should have removed the music at third-party fan testing clips because they're quiet. For a work around, you can listen to the mouse click sound in the clip, regard it as a base sound to compare. I'm sorry for this this inconvenience.
I know I am 9 months late - but the number of issues and DIY requirements on Dell stupid connectors... is why I am always sticking to Lenovo if I have to take OEM PC - no matter if SFF desktop or workstation - because Lenovo left all fan connectors as it should be, with 3-4 pin standard and not some proprietary trash like Dell did...
I upgrade an old HP rp5800. Max cpu i7-2700k. Max ram 32gb (16 in doc...) 256gb sdd + 2x 6 to 3.5 1660 ti with little Undervolt and overclock so max 120w Otiginal 240w psu Windows 11 with atlasos Future? Update gpu with a 4060 itx when price will decrease..
Thanks for your comment. I haven't measured the power consumption, but the temp at idle is good (~45*C at 26*C ambient) so I guess the power consumption at idle might not be high. Also at idle, the CPU fan has grinding noise, that's one of reason I replaced it.
Hi, first of all great video! I also decided to upgrade this pc's fans, but now unfortunately every time I start the pc, the shown fan-error appears during a supportassist self scan dueing the bood. Where you able to disable this annoing self test? BR
Mine has a bit rattling sound too if the big front fan run at high speed. I guess the reason is the unbalance of the fan blades. I can feel the slight vibration. But most of the time that fan run at low rpm so it's not a big issue. If it annoys you, you can replace it with better one like Noctua (of course it needs an adapter to remap the wires as I did).
@@thinhdora I'm struggling to find the size and dimensions of this fan, currently unable to open up my system, do you happen to know if it's just a 120mm in the front?
Sorry for late response. You can follow my steps in the video. If your machine uses standard-sized fans, you can replace them with more silent fans like the Noctua. Otherwise, you might need to replace the whole heatsink as I did. Rememer to measure clearance before purchasing new heatsink.
I would like to point out with your great video while yes noise levels are good and the temperatures are good enough to do with the stock fans are the same fans they use or even just modified versions of Dells poweredge server lineup of fans which are meant for cooling you don't really get the point that these workstations are meant to be in data centers or Enterprise environments reliability and Cooling is sought after more than cooling but still good video though
Thanks for your comment. You're right, maybe I judged it bad because I used it as an PC. As a server point of view, the two noisy yet powerful system fans will keep the temp good for sure.
Umm, no, these desktop workstations are NOT meant for "data centers"! Data centers aren't filled with desktops! They're filled with rack-mounted systems! Source of info: I worked at one of the largest data center clusters in North America.
I quite literally said "and enterprise environments" which include smaller data centers that use these machines for data processing and business use etc, it's funny how you skipped all of that out just to make yourself look smart, but the fact I pointed that context out now you look like a unitard lol
@@wzpu3283 yeah I like the fact you miss out the fact I said "and Enterprise environments"" and *your* data center may not be using them if you do work there but many do for data processing and simulation and business environments as demonstrated on dell's own adverts for these workstations I like it when people cut out the context just to make them self look smart and big and in my opinion bogus claims like working in a huge data centre with no actual proof, but still appreciated for pointing this out :) "if you do work there" then well done I guess not all data centres are the same though I would expect someone like you to know that
