So i recently became the proud owner of this thing:
That right there is a DELL PowerEdge R510 server. It's rocking dual 6-core Xeons and a total of 32GB's of ECC RAM.
By today's standards, this really isn't anything impressive, but that's exactly why i got it. the Xeons in there are the 'L' variant, for low power! This is relevant because i have a 4U server running in the same rack 24/7 with dual 8-core Xeons 128GB RAM and a 2080Ti running on pretty much full load. This means my power bill is high enough as is.
I got it on the cheap from someone who in turn got it from a datacenter where it got decommissioned. Anyway, it now lives happily in my rack!
One problem tough: my rack lives right next to my desk. And this box is not made for silence. Nothing made for the enterprise ever really is.
So yeah, guess it needs some fixes then!
Inside this thing has a total of 5 80MM fans for primary cooling, along with redundant PSU's which both have a 40mm fan. the 80MM fans arn't actually all that bad. They're definitely audible at idle, but it's the PSU fans that really make the noise.
under a heavy load the 80MM's also get to screaming tough.
DELL uses proprietary connectors for all of them, but luckily the pinout is still just PWM. This means i should be able to just cut the connectors and solder them to normal 80MM PWM fans.
The PSU's also use little 4-pin connectors. They kinda look like the connector you would find on some GPU's.
Noctua actually makes some fans specifically for this. They have a couple of adapter cables included with them which should fit in this no poblemo.
So yeah, that's all i got so far. I have 5 80MM Arctic F8 PWM fans and 2 Noctua NF-A4X20 FLX fans on order for this project, and we'll see if cooling is still adequate when i swap them in.
One potential problem is the difference in RPM between the DELL OG fans and the Arctics. The Arctic fans only spin to a max of 2000RPM, which should mean they're nice and silent, but the server expects them to ramp up to 6500-7000RPM.
This means i'll probbaly have to deal with a constant low-RPM warning. AFAIK this server doesn't really restrict anything with that warning going, but you never know untill you try i guess.
The second potential problem is cooling. The original fans push a buttload of air, and the CFM of the Arctics doesn't even come close. The Noctua's in the PSU's should be fine i think.
If it doesn't produce enough cooling for the CPU's, i guess i'll have to figure something out. I hear Alpacool makes some awesome 2U radiators
anyway, that's it. Expect updates as the ordered parts come in.
