Did you make something similar to your RAM block to cool your mosfets?

Yes, but that was on the last NF7-S ... it is not booting now. It was swapped.
I am making another one. It will be made out of solid copper. Much like the video ram WB I just made.

Please forgive me for my laziness, but what was the stuff you used to waterproof your board? I just read through both of your threads and don't really relish trying to pick through it.

Thanks

very nice

Silicone Conformal Coating
It is totally clear. Unless you put a bright UV source withing inches (opaque look in UV)

I read somewhere that someone used liquid electrical tape.

 

[Skeen]

Yeah I've heard about the liquid electrical tape but you have to brush it on and it dries quickly in air. Then it leaves a thick rubbery coating. Pretty neat but its sort of messy and doesn't look so hot.

So ok SCC thanks.

 

[Susquehannock]

Oh yeah!! Love to see this DIY stuff.

Indeed! The Copper scraps they throw away at many construction sites can be
used to make all sorts of great stuff. Especially if you melt it down.

Melt it down huh? I have Oxy/Acetelyne ... what would I melt it into? Some kind of ceramic I presume. I've worked with aluminum bet we used an oven.

Casting copper without a vacuum will result in very low grade copper.

Good to know ... not gonna try that one without my shop vac hooked up.

JK

thanks for the info just the same

Really sick comp

About copper casting - if you decide for it, you ned at least partial vacuum process. Typical vacuum would be the best, but even then, don't expect to get good results with complicated shapes. Anyway, if you decide for casting micro block, silver is a great material. (and small amounts are pretty cheap)

So silver is easier to melt down? I know its a great conductor of heat too.

How come I havn't seen silver plated HSFs and stuff? Is it the cost?

 

[Skeen]

Silver's about $80 for a 10oz bar. For heatsinks, silver's only slightly better than copper, so from a cost effectiveness stand point, I guess Thermalright and the rest say "Why bother?"

I thought it was nickel that was a better heat conductor, hence the reason Thermalright uses a nickel coating on the base of the XP-120.

Very nice work by the way, I love the CPU block, looks very cool.

 

[Skeen]

And I thought people sanded the nickel off of their XP-120s to get better performance.

 

[Brundle Fly]

Hahahahaha, yeah, I saw a thread with that situation in it.

So, if nickel is not better than copper, what is the point of plating the base? I suppose it would solve the oxidation problem, it certainly can't be for aesthetics, it's not like the base can be seen once the sink is installed.

nickel is fairly bad as far as heat conduction goes:
nickel....90.7
copper..401
silver....429

I think they plate with nickel because it looks all nice an shiny at first. a cheap bling bling thing

It does seem pretty silly considering:

1. Its the bottom of the heatsink (but ok its probably easier to do the whole base as opposed to just the top of the base).

2. That whole heatpipe/fin array is so damn big (plus a fan on top) that you probably don't see the base all that much anyway.

I think they do it so your nice expensive CPU can look at itself in the mirror 24/7

I own a SLK-800 and mounted DUAL DELTA BLOWERS. I wouldn't trade my old Thermalright for anything I've seen lately.

Man! That is one(or two) kickazz blower! How loud is it? I know blowers are quieter, but man, that's got to be moving some air. Very nice.
