Now this might be my lack of understanding of the options for controlling case fan speed via software (I do my speed controlling via a hardware fan controller) but I thought you needed the yellow RPM wire going to the motherboard to be able to do software fan speed control via Speedfan or something...

The TriCools that come with the P182 are run off a 4-pin molex connector (red and black wires leading to the molex only to the 12v positions) with no 3-pin connector. The yellow rpm fan wire goes to the 3 position switch, along with additional power connectors. [snip] I don't think this would be wo...

Hello nrlightfoot :) The fans supplied with the P182 aren't the best but may be quiet enough if you control them with software according to temperature rather than the P182's simple 3 position switches -- and it would be cheaper than changing the fans, maybe faster and easier too. Maybe easier for t...

Re: Front, back, top fans...

I have the following "set" of fans: - 2x Nexus D12SL-12 Black and White; - 2x Noctua NF-S12 1200 What combination / placement of fans would give a better AIRFLOW in a p182 chassis? Should I use the highest CFM fans for intake fan? or blowing the hot air out? Anyone have studied this?? The way I thi...

A disadvantage

One disadvantage of this modification is that the PSU is not cooled unless the case sides are fitted -- or it may be a useful discipline!

Hello :) The modification is completed and the system is quieter. Sorry - no camera so no pics. The EA380 PSU's fan controller is good at starting the SFF21E fan in the standard position in the P182's bottom chamber -- starting nicely and running at low speed, better than the motherboard (Gigabyte G...

Wow, samuelmorris, you were quick! :) Can't you just plug the connector on anyway and leave the rpm pin exposed, since its on the outside? Thanks for the suggestion. It's not possible without modifying something; the shape of both connectors prevents it but I'll investigate the possibility of removi...

Hello :) OK, I've opened the PSU and learned four things: The PSU fan is a two wire model so a two pin plug is required to connect the three wire SFF21E fan. The exhaust grille is retained by screws tapped into the fan casing so equivalent nuts are required. The P182's PSU clamp (with anti-vibration...

Thanks all for your input :) Using a PSU with a 120mm fan isn't necessarily bad in a P182. A lot of people use them and swear by them. In the P182 I generally prefer a PSU with an inline 80mm fan just because the air doesn't have to change direction as much. For what you are talking about doing it w...

Linux,lmsensors,fancontrol: script mod 2 get temp by command

Hello :) In case it helps anyone, here is a modification to lm-sensors' fancontrol script to allow it to run a simple command to get the temperature for controlling fan speed. I used it to get a temperature from hddtemp. A fancontrol startup script is also shown below. To integrate with the modified...

Cooling EA380 with P182 fan (Mike C's radical suggestion)

Hello :) Once upon a long time ago in the Seasonic S12 Fan Upgrade thread Mike Chin made a radical suggestion: I know that this topic is about modding an S12 with a quieter fan for use in a P180. I have a radical suggestion. 1. Remove the cover off any (halfway decent?) PSU. 2. Remove the fan. 3. Mo...

Because all the heads move in concert with each other, so only one head is in the correct location at any given moment in time. In other words, a 4 platter drive may have 8 read/write heads, but only 1 of them is in the right place at the right time. You'd need 4 separate servos in order to do 4 op...

That extra platter = more noise, more power usage, more heat, slower drive ready time, more susceptible to shock damage, and more vibration. Makes sense. What I'm struggling to understand is why more platters (= more heads) doesn't translate into faster sustained read and write times. Don't know ab...

Hello :) I just bought one in India. It has both the 5 rib casting and wider ridged cover of version 1, although the cover has an extra ridge. The extra ridge should stiffen the cover and perhaps quieten the drive. The PCB is by DYnamic and its part number is 2060-701537-003 REV A, changed from the ...
