t430 double pipe heatsink

#1 Post by AnalyticalMind » Thu Apr 09, 2020 10:30 am

I have question, is there double pipe DELTA heatinks?

I read this tutorial
https://medium.com/@n4ru/the-definitive ... ff3f6a8e2e

and have no clue on that.
If i understood properly from this single pipe heatsinks
04W3267 / 04W3268 / 04X3787

only 04W3268 is a a DELTA

But from this double pipes heatsinks i dont know which are delta/toshiba ones ane how many versions of each one exist.
04W3269 / 0B41088 / 04W3270

for example
04W3269-04X3788 look like dobule pipe delta
https://www.ebay.com/itm/New-Lenovo-IBM ... 1946346685

but here 04W3269 looks like double pipe toshiba ( noisy one)
https://www.ebay.com/itm/New-Genuine-Le ... 2101252458

Is it possible? there is info in tutorial thatn toshiba/delta have incompatible fans/pipes so it looks strage that signature 04W3269 exist with two differenc delta/toshiba fans on this ebay offerts

Does enyone have knowledge how it looks like with this fans?

Now i have part nr 04W3268
mfg part 0B41087 and have some heat problems but i dont know it this is made by damaged heatsink or old thermo paste... laptop has 15 Celsius degree higher temperatures than other piece of t430.

Yes, there is a double pipe delta heatsink and fan for the dedicated graphics T430. It also works fine on the integrated graphics model - I have one on my igpu T430. Part no O4W3270. I bought mine here: https://www.ebay.com/itm/Lenovo-IBM-Thi ... 2749.l2649.
Also, here's some pics kindly posted by RBS to help you tell the difference: https://imgur.com/a/LJZ9Z.

is it possible to check if my heatsink is damaged in any way? because simpli i dont know if its old thermo paste or damaged heatsink.
Is it possible that old thermo paste could cause +10-15 celsius more in comparison to 100% efficient other piece of t430?

Old paste and dust buildup can cause that. Clean heatsink and change paste. If that doesn't solve it try the heatsink from the other T430.

Those pictures mean nothing.
As said above, clean the CPU and the fan, replace the thermal paste with a good one, like Thermal Grizzly Kryonaut or Hydronaut.
For a how-to: http://www.arcticsilver.com/pdf/appmeth ... d_v1.1.pdf

Note: do NOT buy Arctic Silver 5 (AS-5), it is not very efficient, it is outdated and it needs 200 hours to "settle in"!

Aim of this photos was to ask if this FLAT TIP on heatpipe can be proof of damage in comparison to second heatpipe from other laptop, when there is no such thing.
I bought budget arctic MX2 for budget laptop ;)

Will dezynfection alcohol be OK for cleaning CPU? It contains 70% etanol, 2% of Izopropanol and some little add of glicerin.

I guess it shoooould do the job, however I prefer using 100% IPA. Ethanol is also totally OK, it's that little addition of glycerin I might be worried about, as it's oily, and can leave a thin fat film on the core.
