Hey,
Now that I got your attention with a seemingly silly title, let me tall you what this is about.
A while back in the monster 4k Samsung TV Thread I was talking about how I love my 48" Samsung JS9000 as a monitor, but that the fan noise coming from the One Connect Box annoyed me.
On many Samsung TV's the screen is just a dumb panel with a backlight. All the processing and connections occur on the "One Connect Box" which plugs into the back of the screen. The One Connect box gets its power from the screen using its one proprietary cable.
It looks like this:
The One Connect box has a relatively quiet, but annoying whiny fan in it to keep it cool, which comes on whenever the TV is on. Depending on background noise I sometimes don't even notice it, but other times it annoys the hell out of me, especially since I spend so much time and effort on keeping my desktop quiet.
Back when I was first setting up the TV and noticed the sound and posted about being annoyed by it, munkle (In jest I believe) suggested I should water cool it.
I had a laugh at the concept and moved on.
Now almost a year later, I'm actually building my first water cooling loop, and I was thinking, what if I were to take that board out of its enclosure, and stick a block on it? Maybe it's not that crazy after all?
So, here is what it looks like on the inside:
As you can see, there is the little annoying blower fan, blowing into that black shroud that covers the parts that need cooling.
Under that HSF I found these three chips (the ones with heat spreaders) covered in silver thermal paste. I presume the other components don't need cooling.
Since I probably don't need too crazy cooling performance, and definitely don't want to add too much restriction to my loop, I was thinking maybe I could just use one large low tech block to cover all three chips and attach it with thermal tape.
Unfortunately there are tall components inbetween the chips, so any shared block would have to be especially machined like the original heatsink to touch them all.
It looks like this:
I'm thinking I can just remove the shroud and fan from that heatsink, and attach a waterblock to it, effectively using it as a heat spreader. Again, this is because I probably don't need any fantastic cooling performance.
It looks like this:
So, if I flip it over, and take off the shroud, this is what I've got:
And with the fan removed...
Unfortunately those crappy-ass heatsink fins seem welded to the heat spreader. I could dremel them off, but then I won't exactly get a smooth surface where I can attach a water block.
Again, since I only need basic cooling, nothing like a desktop CPU, I wonder if I could just attach a basic block to the top of the heatsink and be on my merry way.
What do you guys think?
What block would be suited for this task? I'm thinking it doesn't need to have fantastic thermal properties. Basic cooling is fine, but I am looking for it to be copper or nickel, and have low flow resistance, and not cost too much.
Any ideas?
I'm open to any suggestions and/or thoughts regarding this.
