Delidding: nail polish when using non-conductive paste?
 
Do I need to nail polish the electrical points when delidding if I DO NOT use liquid metal, I will be using Noctua NT-H1 thermal paste. It states that it's not conductive.

Please let me know, this is my first delid on 4790k I had for about 4 years now. :-)

EDIT: So here is what I have bought to get ready for installation (for anyone that does it first too)


1. Sally Hansen Color Therapy Nail Polish Top Coat (is not electrically conductive and does not erode the metals like other nail polishes [according to GamersNexxus video and notes]
https://www.gamersnexus.net/guides/3...d-liquid-metal
Buy it here: https://www.target.com/p/sally-hanse...z/-/A-51068156

2. Rockit Delid Tool and Cooper IHS for about 4-5 degrees drop vs Intel's IHS
You can buy it here: https://rockitcool.myshopify.com/pro...s-for-lga-1150
How to use this kit: https://rockitcool.myshopify.com/blo...-new-rockit-88

3. Thermal Grizzly Conductonaut High Performance Thermal Grease - 1g (Liquid Metal)
Buy it here: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

4. Permatex 82180 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker, 3.35 oz. Tube
For putting a tiny bit on the corners to seal the cpu back up.
Buy it here: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

5. Rubbing alcohol 91%, get this high, because it's a pain to remove thermal compound with 50% or even 70% alcohol solutions.

Not if it's normal paste. You can have good results with paste but you should spread it out yourself with a thin layer and remove all the black sealant used by Intel or you'll have small gaps under the IHS. If you use paste do not seal the CPU back up becasue it will dry out and you'll have to delid it again, we use LM becasue the thermal transfer is better but mainly becasue it never drys out under the IHS.

You only need to protect surrounding components if you are using electrically conductive Tim, so using NT-H1 there is no need:thumb:

Keep in mind that the main reason behind delidding is replacing a TIM for something the most efficient and durable, paste will require changing after a "while". Reconsider using liquid metal.

I'd use LM too but I've seen results within a few C of LM with normal paste. As long as you know it won't last 5 years and you don't seal it up, there's really not a downside to just using paste.
It will still last a very long time.

It's very easy to do it,once you have removed the ihs.
So go for the liquid metal and just use polish at the vrms.
I delidded my 4690 2 years ago and temps are as good as they were then.

XLifted 02-14-2019 03:00 PM

Just bought liquid metal because of your advice :-)
Would you suggest putting liquid metal on IHS too, or just the CPU die?

BroadPwns 02-14-2019 03:01 PM

CPU Die and inside part of IHS as well, I didn't do it once and had much worse effect in final performance.

I've done it both ways with the same results but to be safe you might as well paint it on. The best thing I've found for spreading is those cheap paint brushes with nylon bristles. They don't absorb any at all.

Now you do need to clear over the caps. On Haswell the die is very close to the row of caps and the LM spreads out over time.

LM at both the ihs and the die.
But don't overdo it.
Also insualte carefully the vrms and you'll be ok.
I got minus 15C at my cpu.
At 4.6Ghz I hit 100C at 2 mins of prime.Now it won't pass 85C after hours of stressing.
