Thank you! You don’t need all the switches, I’ve done it mostly for fun. You may want one of them though - PWM cut - when it’s disconnected it sets the fans at full blast, when it’s connected the laptop is controlling them. Or no switches at all - whatever the laptop’s fan table says, or if the HWinfo’s fan control works (it does on 8740w) you can control them manually from there, so the PWM is a bit pointless, but no so much if you don’t want additional programs running. For the no switches - you only need Tach connected to one fan, everything else (Power, Ground, PWM) is split between the two. In any case I would love to see what you are going to come up with.

I have two versions. One drives the Acer fans, the other drives the ZBook fans. Both are wired the same - Juice, Ground and PWM come from the same source, while Tach is only linked to one fan and everything is fine. For the ZBook fans (5V) everything comes from the stock connector and it’s been like that for quite some time with no issues. Acer fans (12V) require some extra circuitry since there’s no direct 12V output. BTW they (Acer’s fans) consume about 15W alone at full tilt. EDIT: Here’s the wiring of the ZBook fans: https://imgur.com/gallery/8L0QhNk

Will do, once I put it in a laptop format, so everything is fair and square. I’m estimating 20 to 30*C difference so far. Exact measurements would be next month.

I’ve made a cooling that, at least by initial testing, can cool the extra Watts 🙂
-
It does 🙂 It does indeed 🙂

This is work in progress, but so far I’m happy with the results 😄 The heatsink: https://imgur.com/a/v2gq5dB The fans and their electronics: https://imgur.com/a/mr88Xgn That’s it for now.

- 8740w overclock
- 8740w cooling

I never noticed it. Thanks for the tip!

Thanks! I was looking at the verified ones and they were all DELL. How do you look at unverified vBIOSes?

As the title says - looking for an 8740w US NON-backlit keyboard. OR I want to swap a used US backlit keyboard (pretty good condition, I have two, this one is less used, almost as new) for a NON-backlit one, straight swap no additional payment. You send me yours, once received I’ll send mine. Where’s the catch? Recently I’ve added a second fan in place of the DVD/BD drive and the backlit keyboard is not perforated in this area, where the non-backlit is, so the second fan can breathe. EDIT: Here are couple of photos of the keyboard, as well as comparison with the non-backlit one (it’s a Nordic one). https://imgur.com/a/r9JI1YY

I did a shunt mod, so yeah I hope that this heatsink would help to keep overclocked temps in check.
-
Here’s what I did. Once again - Thank you guys! https://imgur.com/a/v2gq5dB I’m yet to test it how effective it is since I’m still working on the electrical part of it. Once I’m done I’ll post a separate topic.

As the title says, looking for a vBIOS dump of one of these GPUs. Thank you very much!

Dreamcolor Display from HP ZBook 17 G2 into 8760w?

As far as I know the display connector is different. Other than that it should work. -
HP Elitebook 8570W - is it still good ? Hardware modifications
triturbo replied to GuitarG's topic in Custom Builds
Hey there! Would it be possible for you to make a dump of the ColorBoard’s BIOS, or whatever that chip with the blue dot is? I know that it is quite the hassle, but considering that these boards are unobtainable and there is quite possibly no one else on earth both having the board and capable of dumping the firmware, here’s me asking for your help. Thank you! -
Sorry, I don’t think that I can help.
