Question Silverstone LC17 Case - Exhaust Fan of 120mm?

[Oasis Curator]

Hello

I have an older Silverstone case, which had two inbuilt 90mm fans (?) at the rear.
For my new build HTPC, I want to use a single 120mm fan to push air out. There won't be a graphics card but there will be a Noctua short fan for the CPU.

I can't think of somewhere suitable to put this fan as the vent on the right hand side doesn't have any screw holes and it wouldn't work using the two smaller vents for the fans at the back.

Just looking to dampen the sound from fans as much as I can. The power supply is silent so that isn't a problem, although the current CPU has the stock cooler so hoping that would be better with a Noctua. But the two small fans at the back are what I also need to eliminate.

Open to different Micro-ATX cases though.

I have a Silverstone LA17 case but it won't really take a 120mm fan.
The two 80mm stock fans are on the noisy side, especially as there's two of them.
I have a spare 120mm fan so looking to employ this.

The physical space I have to fit it in is only 160 / 170mm high so a lying down case is what I'm looking for really.
Plus the 120mm fan space!
Micro-ATX motherboard.

Isn't buying a couple 80mm Noctua cheaper than buying a case ?

Perhaps, but won't they be noisier than one 120mm fan (that I already have?).
Plus, I don't mind the change in case so it's not particularly about money saving but more noise reduction.

Is this a HTPC or NAS that needs to have a case with the same dimensions as the LC17?

The Silverstone GD05 and GD06 include 120mm fan mounts.

Unknown if 80mm Noctua fans will be quieter. It will depend on RPM, fan design, mounting, etc.

Also, your current case can accept 92mm fans as well. I'd just look for some well recommended case fans instead of a new case.
I'd probably go with a pair of these Noctua 80mm case fans and a pair of Noctua 92mm case fans

Also, let's keep it to a single thread.

A HTPC. Previous iteration had stock Intel cooler and two stock case fans exhausting out the back. No intake on the front. PSU will be the same one (a Cool Master something or other - it's pretty quiet so don't need to concentrate on this).

Size Restrictions: Width / length doesn't matter so much but no more than 17cm high.
Country: UK
Budget: Under £100, but for the right one can go over.

Everything at default speeds, or whatever the PC decides it needs (speeding up / slowing down).
Looking for "on the whole" or "generally..." answers rather than exact specifics as those will nearly constantly change.
One 120mm vs 2 x 80mm - both the same brand if it makes it easier (although the one I have is a Be Quiet Silent Wings).

Also, your current case can accept 92mm fans as well. I'd just look for some well recommended case fans instead of a new case.

I could replace the stock case fans but I'd only be replacing the 80mm ones at the back - this needs to be on the quiet side so wouldn't look to add any more.

Technically there should be less heat anyway as there's more room inside now and only one hard drive instead of 4 (+ an SSD) from the previous version.

Fair enough, but in all honesty, when I had my HTPC up and running, I couldn't hear the PC over the audio being put out by either my television or my surround sound system.

Yeah - that's the same here.
It's probably just a case of testing and seeing what the best configuration is.

On the plus side, saving £80 as the Be Quiet PSU I bought (80 gold) isn't particularly more quiet than the CoolMaster (80 bronze) I already had. I know gold is better but after looking at four or so other websites, the difference is marginal.
