T430 Fan Noise - Need FRU for good replacement

#1 Post by CoolRunnings » Wed Jun 05, 2019 10:21 pm

I'm upgrading a whole bunch of Thinkpad T420 and T430's to Windows 10 and found a number of them with bad or terribly noisy fans. I do recall that there were several FRUs available for the T430 fans and that they fixed the noise issue on one of them. I can't seem to figure out which FRU that is. All of my models are the Intel graphics only ones - not the Nvidia models. Could anybody there hook me up with the FRUs for the good model of fan on the T420 and the T430? Also, I'm in the market if anyone's got them for sale. Thanks!

Well if you like hand work and cheaping out, you can consider lubricating the axle of the fans by disassembling the housing of the heatsink, and then attempt extracting the plastic spinner out of the body and dip oil inside the axle hole. It doesnt hurt since worst comes to worst you get a new fan assembly anyways

Here's some details for T430 only - two fan makes used - Delta and Toshiba. Delta fan and heatsink units are quieter - the heatsink cooling fins are greater spaced so that more air flows at lower fan rpm. Also there are less fan blades and wider gaps between them which also keeps noise down. Toshiba units rev higher and have higher airflow speeds through narrower cooling fins. The dedicated graphics units with an extra heat pipe for the gpu fit fine into the Intel integrated gpu laptops - same gap in the roll cage so you get an extra heat pipe to dissipate heat. Thus, it doesn't matter which you buy for your igpu machines. I replaced a noisy toshiba igpu heatsink and fan with a Delta dedicated unit. There is some debate about whether the toshiba with it's noise and faster airflow cools better than the Delta with it's lower velocity but presumably greater volume flow. Any experts out there? Either way, it you're going to put a quad core cpu into your igpu laptop, install a dedicated graphics cooling unit.
Have a look here - https://medium.com/@n4ru/the-definitive ... ff3f6a8e2e and here - viewtopic.php?t=125566#p813724
Part Nos for heatsink and fan units: Delta igpu 04W3268, dgpu 04w3270. Toshiba igpu 04w3267, dgpu 04w3269.

You'll find plenty for sale on ebay or amazon; the toshiba units are the most plentiful. Plenty of sellers put up ads with pictures of both sorts and all the part nos without specifying what you'll get. I messaged a few in my hunt for a Delta unit, and most were selling toshiba. Good luck if you are hunting for a Delta.
