Can someone help me in finding the FRU number for the above or [even better] telling me where I can source a replacement from .. ??
Machine was originally purchased in Germany and is currently in New Zealand .. This model is not supported here and no parts are available ..
I can find the manual but not the FRU part number [I'm reasonably sure it's not 1120] ..
Solved! Go to Solution.

excerpt from Z370 HMM, page 91:
11- KL5 THERMAL MODULE ASSY 35W UMA (Z370), FRU 31049406
11- Z370 Discrete thermal Group TBD
unfortunately no FRU for discrete graphics model assy.
For replacement, please see this 'Z370 Cooling Fan & HeatSink' sales on eBay...
Z370 Service Training Video...
hope this info helps... Zehn

Thank you for the response .. I really do appreciate the assistance however:
I am unable to locate any image of a thermal module for the FRU "31049406" .. I think this is a nesessary step because there appears to be at least two differant parts [at least two models] .. see next comment.
As with above, the part shown in the ebay links is not the "model" of the part I am after [in that it carries an additional cooling pipe & mount [the smaller of the two pipes] ..
The service training video I have viewed .. was not much help [unless I missed something] ..
The service manual [last link] I have seen and the part illustration looks the same as the part I have BUT no FRU number ..

there seem to be a total of two heat-sink versions used for the IdeaPad Z370,
the dual heat-pipe stile for models with an additional switchable discrete graphics chip,
and a single heat-pipe stile for models with integrated graphics only (Unified Memory Architecture - UMA).
The dual heat-pipe heat-sink version can probably also be utilized for Z370 UMA models,
albeit with the second mounting plate unused.
What CPU and GPU is used in your Z370 machine?
Fan-bearings will wear out over time, but there is no wear on a heat-sink, it just needs periodic cleaning
and eventually new thermal paste applied, why do you need to replace the whole assembly?
The service video and the HMM are intended for service engineers and sometimes may seem sketchy.

I would need to check the current device but do not thinkl there is sufficent room to take the additional pipe [and I don't think I want to consider removing it] ..
The device has an i3 and uses integrated graphics ..
The main issue is corrosion - the device is typically used in a high humidity area on the coast and there is significant corrsoion of the metal fan casing which I suspect is the cause of exsessive [and irregular] noise ..

well, after some digging I found more Z370 integrated graphics fan & heat-sink assy ...
Good Luck... Zehn
