The only way to appreciate this build is to watch the video first http://youtu.be/EAH_orqEp64

The process of building a PC is pretty boring, it’s just an exercise of picking out compatible parts for the right price. I decided to make it slightly more interesting by submerging the entire computer in a fish tank full of mineral oil.

edit: I added idle and loaded temps to the build, and the minerial oil reached 44 deg C under load, also 35 while idle. Details in my blog post.

Wow, I think that's the first Mineral Oil PC I've seen on here, well done! +1

xx116xx 3 Builds 7 points 53 months ago

There was one maybe a year or a year and a half ago. But they are rare here.

jacobs4525 1 Build 11 points 53 months ago

Just saw this after watching the LTT video about their mineral oil PC. +1

samuelyap 5 points 53 months ago

slick needs to step up his game if he wants to stay in lmg :]

geogeodude 5 points 53 months ago

The second I saw it it reminded me of LTT's Mineral Oil computer.

I honestly and truly think they're absolutely fantastic creations, and this one is no exception. Great job on creating something that is quite clearly pretty hard and time-consuming to make, for the pleasure of the eyes here at PCPP.

I'd +100 this, but it's just a shame the only thing I can do is a +1. :(

Great fricken job man. I've always been curious about these.! Never curious enough to tempt fate and disaster ! Still that's pretty sick man !

Tgenthe 3 points 48 months ago

I guess you can say this pc is water cool....


Veni.1 1 Build 2 points 53 months ago

Very unique build, what are the temps like?

frank26080115 submitter 1 Build 2 points 53 months ago

will do a lot of tests later, the tests will take a while but I'll check back and reply to anybody interested

I can say that leaving Windows on the desktop idling, with the pump off, the surface of the tank reaches 36 deg C after equilibrium

I'll tell you more later

You can reuse the entire rig after that as a cooling system for your car's engine. :D What I like most about the build, by the way, is not simply that it's in mineral oil, but that you added a treasure chest and vegetation and actually make it look like an aquarium. I can almost see fish in it! xD

JustAnotherGamer 2 points 53 months ago

Haven't seen one of these in a long-*** time... Well, except for Linus' channel of course.

Chewikazza 1 Build 1 point 53 months ago

Awesome build!

ajpinton 11 Builds 1 point 53 months ago

You don't see a lot of build like this on this site, I don't think I have ever seen a submersion build here before.


NewBornNoob 1 Build 1 point 53 months ago

Great, but get a better cpu cooler!

frank26080115 submitter 1 Build 2 points 53 months ago

I didn't tell anybody yet, but the GFX card is right up against the front of the tank, and it only fits in that way if I cut down one of the pieces of plastic on the default Intel cooler fan.

NewBornNoob 1 Build 2 points 52 months ago

+1'd mate!

Veizin 2 Builds -1 points 53 months ago

I second that. That CPU's not getting any airflow at all in this case!

hjj174 5 points 53 months ago

The 'case' is full of mineral oil, not air.

Veizin 2 Builds 1 point 53 months ago

So it doesn't get airflow, does it?

timmanser 3 points 52 months ago

It does has cool water surrounding it making the processor so cool that it is cooler than airflow. Also I would suggest, do not have double glass is that case.

Geode1010 2 Builds -2 points 47 months ago

You mean a water cooler...


pchaplo 1 point 52 months ago

This is the coolest build ever. Drooling over your fishtank creativity! I came back just to see it again. +1M ps: thinking of weighted scuba diver blowing bubbles in the oil :)

GreasyLoL 1 point 38 months ago

This is beyond unique x....x

memewaffle 1 point 31 months ago

Do you have to disable all the fans with this? Also, how does the mineral oil actually cool it?

Gooberdad 10 Builds 1 point 29 months ago

Late, but wow. Cool build.

Thunbs up.

inkster1013 1 point 7 months ago

are you selling?

Rashiq 0 points 53 months ago

DAT PC THO!!! And his maker is nuts!!! LOL...+1+1+1

SpecificAlduin 2 Builds 0 points 49 months ago

WHy the Core i7 4790S? For 30 more bucks the 4790k would give you much better performance.

GentlemanShark 1 Build 2 points 36 months ago

The 4790s is much lower power.

SpecificAlduin 2 Builds 0 points 36 months ago

True. Also old comment revival.

GentlemanShark 1 Build 1 point 36 months ago

Yep, I've been using this as a guide for my new build.

Bladedrummer 4 Builds -1 points 53 months ago

How much of the GTX 970 did you cut off? How did you do that without breaking it? I have the same exact 970 in my work computer and it is huge, so I am guessing you cut like 2/3 off of it.

frank26080115 submitter 1 Build 1 point 53 months ago

I didn't cut the card itself, only part of the plastic covering the heat sink to get more oil flowing

You can't just cut a circuit board

"I can save some space if I just chop off these 2GB of RAM"

LOL no it doesn't work like that

Bladedrummer 4 Builds 1 point 53 months ago

I was assuming you cut the heatsink, not the PCB, duh...

Bladedrummer 4 Builds 1 point 53 months ago

I also see that it's not the same GTX 970 but a Mini ITX version of it. I wasn't aware those were available.

frank26080115 submitter 1 Build 1 point 53 months ago

I saw that Gigabyte was releasing it in November, I waited for this card specifically, it lined up nicely with black friday but not much else was discounted, I didn't save much money

asunax -3 points 53 months ago

I am surprised you won't be overclocking that thing, you have submerged it in mineral oil but you have a h97 board.

sajiin 5 points 53 months ago

He has a locked processor so even if he had an Z97 board he would still not be able to overclock it.

beepic117 2 points 53 months ago

It's not a really good idea to overclock with mineral oil. It'll decrease the cooling capacity of the rads quickly if the CPU gets hot. I'm pretty sure that's why he got a low-power i7.


frank26080115 submitter 1 Build 1 point 53 months ago

Correct, I picked the "S" CPU with lower TPD and the ECO motherboard that supports it, for the purpose of keeping temps low.

beepic117 1 point 53 months ago

Yes! LOL. I'm good at reading minds. :P

asunax 1 point 53 months ago

Sorry, my mistake lol. I forgot that S cpu's are locked processors, but nice to know that mineral oil is not good for overclocking. xD

frank26080115 submitter 1 Build 1 point 53 months ago

Mineral oil is good for overclocking, if you use enough of it, but I chose to use a 2.5 gallon tiny tank.

The Puget kit is 5 gallons, and with proper planning of the path of oil flow, it can be great for overclocking

But only if you have radiators!

Veizin 2 Builds 1 point 53 months ago

I was thinking as well that the clocking possibilities would be immense, but apparently they're not. Oh well#
