What website is that?🤔 

 

Yea, that makes sense, the IR-Webcam seems considerably larger than the other one… but all that can wait😅 I‘m just glad I‘ll have it up and running tomorrow, once the pads arrive!

 

thank you all for the help so far!

Be very careful when replacing thermal pads because if they are not the correct thickness you will have a big problem.

 

If any pad is too thin, there will be no contact with the heatsink; if it is too thick, it can impair contact with other pads and the CPU and/or GPU.

 

I recommend measuring the thickness of each original pad with a caliper and using soft pads.

 

Or use good quality thermal putty and you shouldn't have any problems.

Guys, can i change my 60Hz (1080p) screen to another faster (120,144,165Hz) on my 7530?Maybe from other Dell's model.Now I have installed a Quadro p3200 with nv-192 radiator, perfomance is very well,using ptm7950 on cpu and gpu cristalls,and Honeywell HT10000 thermal putty (10Wk*m) on vrm.Now I play games with v-sync On (in game setting, global in nvcp works worse), without fps limiter, low latency mode is ON (Ultra does not work smoothly, with micro stutter). So the input delay is not huge, my games can be played in full but I'll want to minimize the delay as much as possible.

You can!  The parts you need are:
- 40 pin display cable
- IR camera module
- Screen bezel (The bezel for IR cameras has a different privacy cover mechanism)
- Double-sided LCD adhesive, similar to this:  LCD Adhesive on eBay

- LCD screen with 40 pin narrow (0.4mm pin pitch) signal interface.  Screens from contemporary 15" Alienware laptops will probably work, but always check with Panelook first (see a few posts up)
