When my first CPU fan on Y500 is broke i replaced it on something compatible (non-original) and planned to replace it later on original. Since that time happened a lot things, but i still using that non-original fan. But i did some research and here is what i founded:
I. ORIGINALS
1. Forcecon (marked as FCN on fan)
DFS5413005MH0T-FC1C (5V - 0.5A)
Spotted in: Y400, Y500.
2. Asia Vital Components (marked as AVC on fan)
BNTA0612R5H-P007 (5V - 0.5A)
Spotted in: Y410p, Y500, Y510p.
3. Sunon (marked as SUNON MagLev on fan)
MG60120V1-C230-S99 (5V - 2.25W (0.45A))
Spotted in: Y410p, Y500.
So, which to choose? Any recomendation? Maybe there also unexpected way (completely diffirent fan from another company for another laptop)?
