Re: Largest 5400rpm storage?

I can't say I'm all that keen on SMR really, having read about it. I'm not likely to suffer too much with the write performance itself, but the actual concept of it unnerves me...

Re: Largest 5400rpm storage?

It's bizarre, as 5400rpm even shows in the drive stats. The fact that the competing Seagate disks are also 7200rpm once you reach 8TB tells me that for whatever reason, 5400rpm presumably doesn't work too well for the largest capacity disks. It's a nuisance as I was hoping to shrink my drive count b...

Largest 5400rpm storage?

I've been using some WD80EFZX disks for a while now. They're definitely a lot noisier than the smaller WD Red/Green disks, which I assumed was simply due to the high platter count or possibly a quirk of the Helium design. The 6TB disks are pretty loud during seek but quiet during idle. The 8TB disks...

Re: AMD & Intel 65W Stock Coolers

Quick question - if the i7 6700 cooler tops out at 2000rpm and the same cooler is used throughout, how come the one supplied with my i5 6600 seems to top out at 3500? It makes quite a din at that speed...

Re: Software-adjustable ventilation for storage server

From the manual: http://i.imgur.com/HOELCqe.png I'm curious about the phrase "The speed control function requires a fan with fan speed control design". Is this implying only PWM fans can be speed controlled? If so it doesn't explain why the Nexus 80mm fans are operating at less than half speed where...

Re: Software-adjustable ventilation for storage server

Quest_for_silence: Noted re: Voltage/PWM control - the fan without any speed control is SYS_FAN3, a 3-pin header. The other two that are listed in the BIOS (both the adjustable and unadjustable) are both 4-pin headers, so presumably they are both PWM headers, and SYS_FAN3 is just a straight feed to ...

Re: Software-adjustable ventilation for storage server

The fans are already set to 'silent' in the Gigabyte BIOS, but I'm not too confident, as the SYS_FAN3 socket is not even listed in the BIOS for fan control, and the settings for SYS_FAN2 are ignored, 'silent' is interpreted as a continuous 12V, whereas SYS_FAN1 is adjusting the speed. I will try the...

Software-adjustable ventilation for storage server

I am running a storage server using fundamentally normal desktop hardware inside an XCase RM420 (almost identical to Norco 4220) 4U chassis and with an Adaptec 71605E HBA in the PCIe slot, no dedicated graphics. At the time I recently upgraded the hardware (currently an i5 6500 and Z170-HD3P) I also...

Re: Best way to electronically control high-current fans?

OK, the NZXT Grid+ is in. Installation was pretty straightforward, the 'click-in-place' velcro-style pads seem to work well, but time well tell how long the adhesive on the other side lasts! Ideally I'd have liked to see some screw-based mechanism where you could use a 3.5" or PCI slot, but no matte...

Re: Suitable replacement for NX-5000 R3

Understood, thanks for the insight. I did consider a Seasonic X-650 off Scan for £106, but as it's looking like this may not be my only expense this month, I think I'm going to go with the RM650 for £80. If it turns out too noisy I can always replace it with something else later down the line and st...

Re: Suitable replacement for NX-5000 R3

Sorry, I meant £80 for the RM650 - not so bad I suppose, is £79.99 on there so I'll probably try and amazon locker it. Saves me having to use bybox, which is a little less convenient.

Re: Suitable replacement for NX-5000 R3

CA_Steve: Point well raised, yes it's basically the UK version of the Kill-a-Watt measuring AC draw. Correct me if I'm wrong here, but is it not the actual process of spooling up the disk platters to the 5400rpm speed that prompts the highest draw, instead of the buzz routine? If that is the case, t...

I haven't owned a retail Seasonic, but did own a Corsair HX520 for a while which was very quiet, but did suffer some vibration that became obvious due to the very low noise level of the system it was housed in, and a lightweight aluminium casing. Interestingly the CX430 in that case now does not suf...

Re: Suitable replacement for NX-5000 R3

Thanks for the insights guys. I'm definitely going to be heading down the single-rail route I think, but the definitive role for this server isn't set in stone, I'd like any PSU that costs me a fair amount to be capable of handling a change in role for the server later down the line, e.g. if it shou...

Re: Suitable replacement for NX-5000 R3

Yeah the Nexus is obviously one such unit that runs 300-400rpm most of the time. The Zalman seems to run about 700rpm and that's also fine, even for a 140mm fan, the thing is effectively inaudible. I think I'd prefer that to a semi-fanless unit by the sound of things, for the reason you specified. A...

Re: Suitable replacement for NX-5000 R3

I don't necessarily need it fanless, but going straight from fanless to 1000rpm seems a bit excessive don't you think? I'm not particularly keen on having a fully fanless unit, as since this server is mounted upright, this makes the system a traditional PSU-at-the-top hot box scenario. The CPU heats...

Re: Suitable replacement for NX-5000 R3

The case uses backplanes which connect four drives via a single (or pair) molex connector - the drives are not powered using traditional SATA connectors, and on a modular PSU I would only fit a minimal number of those to run the O/S SSD. Thanks for the links, call me suspicious but given the quality...

Yeah the case in question has a top-mounted 3.5" bay spare on the inside, so I'm hoping to attach a controller like this to that somehow.

Re: Best way to electronically control high-current fans?

That looks really good actually, I can't see me breaking 5W per channel in practice as there are only 5 fans I'd want to control with it. It'd need a header-based USB cable which isn't evident from the product page, but apart from that looks perfect - I'll look into it, thank you :)

Hi all, I'm looking for a viable method to control some fairly powerful (but not exactly extreme) fans in my 4U file server. Sadly the version of the case I own predates those that were supplied with built-in PWM fan control. The 120mm fans are around 2000rpm at max speed. I can potentially replace ...
