Is there any downside to using liquid metal for cooling

Thermal Grizzly Cryonaut and Arctic Silver 5 are pretty good. 

As the title states, I'm trying to find if there are any downsides to using liquid metal cooling. I'm planning on buying an I7 9700k and OC it with custom water cooling, but so I don't waste money I am trying to figure out what to use for

"Thermal paste".

Potential that if you apply too much and a drop comes out of the side it will fall on something important and kill your PC.

 

Also apparently it needs to be reapplied every year or so if it dries out.

I've also heard that you'll be a lot cooler with heavy metal, or even death metal.

If you don't mind changing it annually and taking the risk of a leak killing your components then yeah it's fine but if you don't want that then just get a good quality thermal paste.

There is also risk of seepage as it is a liquid, thereby it can leak out regardless of whether you applied to much or not, .

This is your 2nd system and you're going for a full custom loop and a 9700k? That's not an issue I just hope you know what you're doing because custom loops are a pain in the ass to install and can ruin your PC if not installed correctly.

So do you guys have any suggestions for good thermal paste "no restriction on cash I just want the best so that I can get good thermals when OC"

Another thing worth considering is a graphite thermal pad, it is reusable, never needs to be replaced, and perform almost as well if not as equivalent to most high grade thermal pastes.

I've watched lots of build guides and I'm using an EK custom loop that I have seen one of my friends use, I'm hoping he might land a hand if I run into any problem. So I think its gonna go alright

That sounds good to me, you seem like you've been doing your research so I can see it going alright.

I've heard that it scratches the cpu's heatsink.

It does to some extent as it includes synthetic diamonds for efficient thermal conductivity.

Ok well thank you all for your replies, I think that il probably use Thermal Grizzly Cryonaut.

MX-4

NT-H1 or IC-diamond are good too though.

The amount of space between a CPU and heatsink when properly mounted is a fraction of a micron.

The surface tension of the fluid makes it impossible for it to "seep out" due to gravity.

The only time it will seep out is when the heatsink is initially being mounted, when it will squeeze out all the excess.

Get the 1 oz syringe, that can cover the cpu 2-3 times.  It doesn't store well once opened. It'll be better to get another another 1 oz application 12 months down the road.

I think that applying thermal paste once for it to last a couple of years is more worth it for the marginal performance and dangers of liquid metal cooling.

Agreed, I have only ever seen ppl use liquid metal under the heatsink after delidding too.

 

Are you going hard line or soft tubing for your loop?  It is okay to run a mixture of the two or just doing soft to make it easier to service components and when upgrading.

Think going for a soft loop since I'm not that familiar with custom loops.

Cool, are you thinking about piecing together all the parts separately or getting a kit like This ?

Id like to get the parts separately but still cheap like 200-400$ from Ek so prob some of their aluminium products.

Cpu block, pump/reservoir combo, radiator, tubing and then fans will take you close to if not over $200.  That is a cpu only loop, full cover gpu block will be another $150 by itself.  Add in all the fittings and plugs and you'll certainly be at $400. Just be sure you know what you're getting into, custom loops require much more maintenance than an aio.
