Voron Headbed

My LDO Voron 2.4 350 Rev D started smelling very bad after approx 200h of printing over the last year. Please don't come with comments like "usual ABS SMELL". It is definitely not the ABS! This smell is really horrible and spreads arround in the complete house.

The reason seems to be using the heatbed at 120deg for drying silika for a long time-period (approx 8h).

Now I want to replace the heatplate of the bed.

Fabreeko offers heatbeds with suitable glue, or probably even without. But they are currently out of stock and I dont know how to order from germany (probably quite expensive, when including shipping and taxes)

Does anyone has experience in using heatresistors for heating a 3D printer bed? My idea is as follows: Drill 60 M3 threads into the back of the Aluminiumplate to fix 30×50W heatresistors, which should be sufficient for heating with 450W. I would like to give that a try, but:

• Is there any conductive paste on the market, which does not smell (!)
• Does this work with the cartographer probe?
• Any other possible trouble, I have overseen?

I ordered 30 100Ohm resistors + HY510 thermal conductive paste and a few meter silkoncable Isolation is planned by using the outer insulator of the 3 wire silikoncables and glue them by using kapton-adhesive Thermistor is not yet planned, probably an old one of my extruder, with a drilling at the side of the print-bed.
