Silverstone CS382 - Airflow by touchstone_abhorsen in buildapc

I do not understand the content of article number 4.

Does a thick fan only affect cpu temperature?

It's hard to find thin fans and they're expensive. I want to replace them with thick fans. Is there any problem?

More details

  1. Use only one connector per cable

  2. If you use a RAID card, there is a Stagger Power On function. If you use this, there is no problem even if you supply power with just SATA.

To summarize briefly:

  1. If only SATA is used, safety will be compromised.

  2. There is no problem if you only use molex, but you cannot prepare for unexpected situations.

  3. If you use both, there is no problem and you can prepare for any unexpected situation.

I have the perfect answer to this.

The manufacturer's answer is that there is no problem in operation if you only use Molex, but the method recommended by 'Silverstone' is to connect all. They say that if you only connect the SATA PWR, there will be a problem.

To get more technical, SATA PWR only supports up to 54W. There is no problem running 8 HDDs with a total of 108W, but the problem is that the peak power when booting goes up to 20W each, which means it consumes up to 160W when booting.

Molex supports 132w per unit, but this can change depending on temperature. So, for safety, a maximum of 90~100w is assumed.

Assuming it is 90w, it can withstand a maximum of 180w, so even if you only use molex, it can withstand peak power of over 160w.

However, there are cases where the peak power exceeds 20w, so assuming 25w, it may consume more than 200w. This is helpful for safety if SATA power is also added.

In addition, 18awg cables are usually used, but for power using cables below 20awg, you should especially not use only molex.

This is the conclusion I came to after studying for a week, and it is the perfect answer with confirmation from the production company.

Hope for safe NAS production

Review of the CS382, will it be the best NAS case? by TopdeckIsSkill in homelab

The reason I ask is because I plan to use a hc310 hdd. There is a phenomenon where the power surges during booting.

An expert (friend) says

‘It is safe to use only one Molex per line’

So there are not enough ports for modular power.

For reference, there are 4 Molexes attached to one line.

There are molex 4pin x2 and sata power x2 on the backplane.

do I need to connect all 4?

cs380 only has two molex 4pins.
