Compatible cpu fans for T520?

2015-05-30, 10:23 AM

I have purchased a used T520, which I am very happy to say is very quiet in comparison to the L520 I used to have.

 

Because this is a used machine, with some years of use on its back already, I am considering to purchase a few parts i could easily exchange myself if something went wrong.

One such part is the fan, which could fail or start whining...

 

My T520 (integrated graphics) has a Panasonic UDQFLZR21FFD fan, DC5V 0.23A

 

I am wondering if Lenovo uses any other manufacturers for cpu fans on the T520 or just this specific Panasonic model...

 

Personally, because the fan on the L520 had a fan that drove me mad (a delta fan I think), I had purchased a slightly different fan, that Lenovo used to put in the SL410 SL410K SL510 SL510K L410 L412 L420 series of laptops, a Panasonic UDQF2ZH82FQU DC5V 0.21A fan.

 

I did not get to use the fan actually, but I am wondering if the slight difference in amperes would matter significantly if I were to use the latter fan in case of T520 fan's failure.

 

Unfortunately the Panasonic UDQFLZR21FFD fan does not seem to be separately available (unless when sold with the complete cooler+fan kit.

Solved! See the solution

You will find the list of supported CPUs starting at the bottom of page 137: http://support.lenovo.com/de/de/docs/MIGR-76854

Thanks for your reply, but I am pretty sure this is not what I asked.

i did not inquire into compatible CPUs, but cpu FANs used in T520.

Lenovo's HMM states the following FRU numbers for coolers (heatsink + fan) for integrated graphics:

 

  • 04W0439
  • 04W1578
  • 04W1579
  • 04W0440
  • 04W1580
  • 04W1581

Unfortunately I cannot say which brand will be each. And the Lenovo manuals do not specify FRU numbers for the fan only. I would check in eBay and similar shops. If they provide original pictures the manufacturer of the fan may me visible. For example this listing: click me! seems to have a Delta Electronics fan.

Thank you for your answer.

It seems that Lenovo uses fans with different specifications, at lease for the i) integrated graphics and the ii) discrete graphics laptops.

- The integrated graphics T520 uses at least one fan, the Panasonic UDQFLZR21FFD, DC5V 0.23A. I don't know yet if there are others as well.

 

Unfortunately though there seems to be almost none information about it on the web and it is not sold separately

 

- The discrete graphics T520 uses at least one fan (as per your link), a Delta Electronics KSB06105HA, DC5V 0.4A.

 

 

My previously purchased Panasonic UDQF2ZH82FQU DC5V 0.21A fan, that Lenovo used for the SL410 SL410K SL510 SL510K L410 L412 L420 series is quite close to the specifications of the aforementioned integrated graphics T520 fan; so I guess if the T520 fan fails I could try it at least temporarily.

 

 

But I guess there is no other way of knowing but doing what you proposed, i.e. searching for the FRUs of the heatsink-fan components to find out what specific fan models Lenovo is using.

 

I am going to mark this thread as "solved", but if anyone discovers fans other than the two mentioned above, he/she could still reply.
