Hi I'm about to delid my intel 4790K and replace the TIM with Grizzly Conductotnaut liquid metal but wanted to ask what to use to cover up the cpu die resistor on 4790k ?

Liquid Electrical Tape or Ultra Black RTV Silicone Sealant Adhersive?

Is RTV silicone conductive at all?
Does it contain acid when cured?

The 4790K still gets good results from delidding.

While they improved the thermal issues that the 4770K had, replacing the TIM for liquid metal is a noticeable improvement.

Admittedly though, only worthwhile if overclocking.

The problem is I want to Overclock my i7 4790K to 4.7ghz but I'm running on a Air Cooling a Noctua NHD14 with dual NF-P14 FLX fans.

Since AIO liquid cpu cooling is exspensive over here in Australia like $200AUD for NZXT X62 Kraken.

Basically I want to delid my CPU and change thermal paste to liquid metal to reduce temps by 20°c decrease to give me more headroom for overclocking since I'll be bumping up my volts=hot.

getting a 20c reduction is an absolute 'blue sky' scenario, dont count on it.

On average, I see people getting anywhere from a 8-12c reduction in temps under load

Ok the problem is I have a stock intel i7 4790K never overclocked before and want to at least OC it to 4.5ghz for 24/7 use on air cooling noctua NHD14.

Things will get very hot when bumping the voltage to reach 4.8ghz.

That's why I'm asking is delidding worth it IF im only using air cooling to oc my CPU.

I'll be using Thermal Grizzly Conductonaut liquid metal since that's the best one to get -20°c in temps from stock temps.

This guy delidded his i7 7700K and used thermal grizzly conductornaght.
Overclocked to 5.0ghz and saw a
20-30°c degrees decrease different, here's the video on YouTube:

the 7700K's see a bigger gain as they tend to run warmer than the 4790K's

it's doable though, but every CPU is different, so just don't count on getting huge results
