Quite recently, my beloved Delta KFB1012HE died abruptly, which made me more interested in the different models available for the Slim (specifically for the 20XX/21XX/25XX).
There are some topics and videos about FAT's fans models comparison (efficiency, noise, etc...) but practically nothing for the slims. Scattered data, at best.
(Or did I miss something... ?)
That's why I'm opening this thread.
Feel free to contribute !
If possible, share your results like this :
- Fan model
- Slim model
- CPU/GPU temps in °C after 1 hour idle in Movian (yes, Movian. The XMB is fine and all, but is it a static wallpaper ? Waves ? Waves + sparkles ? etc...)
- Fan speed (would be better to set a manual % for this test, like 40%).
- Room temperature in °C
If you have ideas to improve the methodology, I'm listening !
I think this should be sufficient, but... ¯\_(ツ)_/¯
Don't forget to let it cool down between two tests.
Of course, the ideal tester would be someone with multiple fan models to try in one console, to get more significant results for comparison.
But even if you only have one model to test, it's still something. We can always try to cross-check the data later.
About noise, it's more complicated since there is a huge part of subjectivity. Different sensibilities for different frequencies, etc...
Still, feel free to share your experience.
There are 5 models for the 20XX/21XX/25XX :
• Nidec G10C12MS1AH-56J14
• Nidec G10C12MS2AH-56J14
• Delta KFB1012HE
• Delta KSB1012HE
• NMB-MAT BG1004-B045-P00
...and only one fan for the 30XX series, so nothing to compare :P
• Nidec G80E12NS1ZN-56J14
My personal results :
• Delta KFB1012HE
- Slim 2504A
- Temps after 1 hour idle in Movian : CPU: 46/GPU: 46
- Fan speed : 40% manual
- Room temperature : 21°C
• Nidec G10C12MS1AH-56J14
- Slim 2504A
- Temps after 1 hour idle in Movian : CPU: 49/GPU: 50
- Fan speed : 40% manual
- Room temperature : 21°C
• NMB-MAT BG1004-B045-P00
- Slim 2504A
- Temps after 1 hour idle in Movian : CPU: 49/GPU: 50
- Fan speed : 40% manual
- Room temperature : 21°C
The Delta KFB1012HE is significantly better for cooling. A shame that mine died...
As for the noise, I'll say that the Nidec is probably the quieter of these three. The Delta one is bearable, a bit more high-pitched though.
The NMB is the worst for me.
It's nice to create an 'original' design with more blades and all, but it would be even better if it actually improved something. Unfortunately, that's not the case at all.
The simpler Nidec G10C12MS1AH-56J14 is as effective and even quieter.
I found a Nidec G10C12MS2AH-56J14 that I should receive soon. Can't wait to see how it performs !
Also, interesting things I noticed:
The two Nidec have different amperage, okay. That's a noticeable difference. Maybe the G10C12MS2AH-56J14 will perform better ? I don't know. That would be logical.
But apparently, there isn't such difference between the two Delta. Same amperage, same blades count.
So, maybe they modified the shape of the blades ?
Or... the first model was defective ?
Whatever.
If someone has a Delta KSB1012HE (or even better, both Delta fans !), I'd love to know its effectiveness !
I'll try to find one but it seems to be rare where I live
