fans

I got some arctic cooling 6K RPM fans to replace the 15K RPM fans that were in my Datto Server, but they run at 3K RPM instead of 6K. Looking at the datasheet the fans will run at 3K RPM @ 7v, and hooking the fans up directly to 12v Does give higher fan speeds. But i haven't 100% confirmed...

I have an older 16Bay server chassis from Supermicro. I can't find the exact part number, but it looks identical to this: SuperMicro 836BE1C-R1K23B 3U 16-Bay Server SuperChassis I've gutted this system and replaced the guts with those of my old desktop computer (i7 3770k, Sabretooth Z77, 32GB...

Hi everyone, I have 2 unraid servers that get too hot when parity syncing, especially in the summer, so it is time to change the fans (original fans that came with the case). I like the cases I am using, and you cannot find anything similar these days, but due to their idiosyncrasies, I am not...

Hi guys, I consider purchasing a rackmount UPS (SMT1500RMJ2U - same as the model in the title but for the Japanese market, e.g. 100V). Does anybody know how loud the fans of these units are when they are NOT running on battery power? APC states a value of 46db(A) on their website which would...

I just got an old CSE-835 and I already fell in love with it as I can use 3.5" and my 2.5" together. It's just the fan noise from the 'fan-bar' which bothers me already. Ok, I can set the fan speed in the bios, but that's just a statical solution. Therefore I'm already working on a 3D printed...

Finished my upgrade to a CSE-847 thinking I could throw all my disks into one unit, use one MB, and max the ram and be in media storage heaven. Well, I didn't think things though, filled the unit up, turned it on and found the fans screaming their way into my ears. I've tried various...

Hi, I recently acquired a Supermicro 846 chassis and need it to be quiet as possible (I'll be sitting 6 feet away from it). I was looking into doing a full fan swap of the current FAN-0127L4 to the much quieter but much weaker FAN-0104L4. I've also seen some suggest the FAN-0074L4, but I notice...

Hi, I just grabbed a cool server for pfSense with a X9SCI-LN4F Supermicro board and a E3-1230 v2. Everything seems to be fine except for the fans. They sound all like rubbing sandpaper and they are almost EOL and have their dead-end very close. The fans currently installed are SUNON...

I've got a full-length 4U server case, so I've got plenty of room to macgyver it and get any size of fans to work somehow, but I need to both create decent suction to pull air over my hot-swap bays and cool what will probably be a big passive AMD EPYC cooler. I can't seem to find anything to...

Hi there, I just bought a Supermicro X11SDV-4C-TP8F, and I really like it. The active cooler I bought from Supermicro is extremely noisy, though, and I wanted to have it a bit quieter. I read lots of blog posts about setting up the upper and lower threshold of the fan speed via impitools, as...

I'd like to replace the Delta PFR0912XHE-BC90 jet engines with something less crazy, and make this server more home friendly. I've tried hooking up ebmpapst 3252J/2HP but they run full speed and ILO reports fan error. The only suitable datasheet i can find for the delta fans are PFR0912XHE-SP00...

Hi, Don't know if anyone would know, but is it possible to replace the PWS-721-R1 PSU (in a supermicro case & mobo) with a quieter one? I've attempted shoring pin 17 and it does not seem to be working, so looking to get a quieter fan... but I am not sure if the power supply will allow that - or...

Hi, I purchased a "killer" combination: Supermicro X9DR3-LN4F+ motherboard (I didn't know it was an EE-ATX) and Supermicro CSE825TQ-740LPB chassis. I've installed Noctua NH-L9X65 on the CPU's. The Chassis fans are the standard Supermicro 7000 RPM fans I checked the following: I used ipmitool...

Hello all, Frequent lurker here. I think first time posting. Gradually putting together a larger post with my complete build, however I have a couple of loose ends. I’ve reviewed some of the threads on the CB3 but some info I haven’t found or I haven’t seen a direct comparison in my use case...

Hi guys, I'm having issues setting fan speeds on a 4027GR-TR Supermicro system. System has 8 fans for both CPU/GPU/chassis cooling, and are controlled via the IPMI. I've followed this guide from PigLover but it doesn't seem to work with this system...

Im in need of some assistance in regards to the CPU temp threshold of my supermicro motherboards. Useing the ipmitools on my linux laptop im trying to lower the CPU temp threshold. The issue is that the change is never acctually implemented. Even though ipmitools says that the temp is...

I got tired of the noise with my SuperMicro X10 Server (4027GR-TRT), but didn't want to get into involved hardware fan swaps which still may produce unsatisfactory results. For reference, the "Optimal" fan setting decided to run half of the fans at 8000RPM at idle, and the other half at 5000RPM...

Hi, I have a supermicro 2U case which I love, but it's in my office and it's a little loud for office work (can even be heard over my switch, which is also loud). My girlfriend has also been complaining about it recently. I replaced (most) the fans in the switch with noctunas, which I had to...

Hi All, I've been doing a bit of reading on how to use impitool to adjust the fan thresholds on my motherboard, to prevent the spin up/down issue that some people have previously reported. The basic steps I took were as per Decrease Supermicro IPMI Fan Threshold This MB has 5 headers, FAN 1...

I purchased 2 x Sun Flash Accelerator F40 recently, and while they don't arrive until Thursday (and I don't even have a baseline yet), I'd be willing to wager a few bucks that I may need to manage air flow for the PCIe cards. I suggest that as: (a) others have noted they run very hot, (b)...
