Am I using the right fans? Nanoxia DS1

post #1 of 9
Thread Starter 
I have a Nanoxia DS1 which I'm cooling with 3 fans. I have only the bottommost 3-capacity HDD caddy, so that leaves a gap between the 5.25" bays and the HDDs. I'm cooling it as such:
1) Gentle Typhoon AP-15 in front of gap (so blowing at the inside of the case)
2) SP120 performance in front of HDD caddy
3) AF140 quiet exhaust

The logic was that the SP should push higher-pressure air through the HDDs, while the GT would just suck a lot more air into the actual case. But HDDs don't need that much cooling and on top of it, my temps are pretty good (I have a Silver Arrow on an 2500k and idle temps are around 35C in a pretty warm apartment, with the fan controller always on the lowest setting).

I have a bunch of fans laying about. Another SP120, a few GT15s, the Nanoxia stock fans...
Mostly I want to keep the quiet, but making sure I have the best cooling available for the noise.

What would be an ideal combination of fans here? I don't need more fans on the case. It's a quiet case and I love it this way smile.gif (to be fair I do not understand the point of non-quiet cases: I overclock just fine on low temperatures, and that's with 3 x fans and a padded case. I never had a non-quiet build though).

New fans, more adapted to what I want, could do as well smile.gif

The stock fans are pretty good as far as i know (someone correct me if im wrong) why not add those other fans to the side and bottom instead? smile.gif

Nah no more fans. 3 is more than enough, I get good temps already and low noise, I just want to see if I can get lower temps with the same or better noise levels with my spare stuff.

I suggest using PWM fans and controlling them with PWM signal from motherboard CPU fan header. This way case fan rpm rise and fall same a CPU fans.. silent at idle / low load but is just loud enough to hear at full load. Everything I build is this way.. and many other have done the same. So far everyone love it with not a single complaint. Oh! Wait! There are complaints. Forgetting to turn system off because it is silent. tongue.gif

Pretty much what doyll said, got myself 3x TY-147's and put them on the CPU PWM with a splitter, works without a hitch

The conceptual problem I have with that setup is my cpu invariably runs cooler than mb and gpu. I'm using Asus Fan Xpert 2 and cpu temp is the only threshold you can set for case fans. But if I put the case fans on separate headers, I can adjust the minimum rpm higher. If I set everything to the cpu pwm header, all fans always run at minimum rpm unless I'm running a cpu stress test. And if I'm gaming, cpu might be at 30c while gpu is 75c+, but the case fans will still be at min rpm because cpu temp isn't high enough.

I could better understand putting case fans on the cpu header as slaves to the cpu fan if mobo controls did not exist and you had to constantly turn fan controller knobs. But using the chassis headers with something like Fan Xpert 2 is so easy. And this way you don't need to run an additional molex or sata line off the psu to handle all fans being run off the same header, which may result in easier cable management. Does for me, I prefer the thin braided fan cables plugging along the edges of the mobo to another flat plastic line coming out of the psu, through the grommet, and tied up in the back area.

As most GPUs are now using PWM fans you can use that PWM signal for PWM case fans too. Not as easy because there is no simple PWM splitter made that plugs into mini 4pin PWM used on GPUs.

Advantage of using PSU powered splitter is there is no power load on motherboard.. and most motherboard fan headers are rated 1a/12w maximum.so about 10w is safe.. but is that for each fan header or for all fan headers? headscratch.gif

Most case fans are in the 0.2a/2.4w.. with safety margin that's 2.8-2.9w... so 3x case fans on a header is all I would consider running.

Without PSU power and with PSU power.

You know I wondered about how I might use that header. Gelid sells a 4 pin to mini vga cable http://www.frozencpu.com/products/13314/cab-454/Gelid_Solutions_PWM_Fan_Adapter_for_VGA_Cards_CA-PWM-02.html?tl=g2c251s1325, and then you'll could use a molex powered pwm splitter (just to be safe, don't know what power load that vga connector can handle http://www.frozencpu.com/products/10350/cab-183/Akasa_PWM_Splitter_-_Smart_Fan_Cable_AK-CB002.html?tl=g2c251s1325) to link a side fan to the gpu.

Although, I'm not sure I want to increase the rpm of a side fan over the gpu. I just want a trickle of air there, not a blast. Maybe for the bottom fan though.

My mobo specifies 1 ampere per header but just to be safe I go one fan per header or use a molex powered smart splitter. There's such a huge variance in fan power draw, two fans with similar rpm one might be 0.2a and the other 0.6.

Here's Mini 4-Pin GPU (Female) to Mini 4-Pin GPU (Male) / 4-Pin Fan (Male) Cable Splitter so we can plug GPU fans into mini 4-pin side of 'Y' and normal PWM splitter with molex power into normal 4-pin PWM side of 'Y'.

Wish this was available in UK. frown.gif

Indeed. No reason to draw 12v from motherboard with splitter available that use PSU 12v power.thumb.gif
