Question about Cooling.

[PlatinumSun]

Now, I think air coolers look ugly. But Ive heard AIO underperform. So what makes AIO's worse than custom water cooling.

And what would I need for Custom water cooling that is good and affordable?

Im going to get a water block for my 980ti or does that only work for AIO's?

Also thermal paste whats the best stuff and is it worth the money?

Custom Loops or an AIO using distilled water or other liquids that are at all water-based; can never go below room Temps.

For Sub-Zero you're thinking Liquid Nitrogen [ LN2 ] which the average person can't afford to use or be trusted to even legally acquire.

not only that, yoyu need to constantly refill the coolers with LN2 and you need special hardwrae like LN2 coolers and heating pads to heat up the cpu so it not getting frozen and below operating tempretures.

Can you get your AC unit in your Vehicle or Home to go below 0*F ?
It's not that simple, nor cheap, or power efficient ...

Getting LN2 license is pretty easy. But yah needing to constantly get more of the stuff is real expensive. Im pretty sure you can get cooling solutions that go below 0. But for a regular above zero custom loop whats the usual price?

you can't. A custom loop doesnt work like a freezer/refrigerator.

A custom loop has a CPU/GPU Block. The heat from the CPU or the GPU will transfer to the Block which will transfer the heat to the liquid. this is a bit unefficient but the only way to hold the liquid in place and make sure that it not fload around (with exeption of dive in cooling).

Once the heat is in the liquid it will be transported through the tubes by the power of the pump. At somepoint it will reach a radiator. The radiator is nothing else then a heatsink. it has many blades made out of metal instead of a solid object to extend the surface area. It actually is not any different then a normal heatsink just that instead of copper pipes from the block to the heatsink you now have the liquid cooling tubes (which are also pipes) that lead through it. From the radiator (heatsink) the heat is transfered into the air which performance is increased by using fans to push room air to the heatsink and push the hot air away.
If you would go below room tempreture the same thign works aswell just backwards. Means: If you would drop below room tempreture with your custom loop, the room would actually now start to heat the CPU up.


Befor you now ask why not to build a cooler like a refrigerator, have you ever put cooking stuff in a refrigarator? proberly not or oitherwise you might would know that this would break a refrigerator in no time.



The price of a custom loops depends on what stuff you use. cheap pure aluminium kits cost kinda less just a 200-400$ while a pure copper or nickel plated build can easily exeed 700$. YOu cant mix up aluminium with copper or nickel plated...

[Bad 💀 Motha]

Well we do have products where they do have copper bases and/or pipes; often then protected by a nickel plated finish so that the copper does not oxidize; but yea with Rads, you'd want something much more solid and as simplied as possible, like solid aluminum, this keeps costs down, and when done right, shouldn't be junk. We even have Engine Blocks made from solid aluminium; why? Well this keeps them as solid as possible, while reducing not just weight, but costs.

For running sub zero ish without non stop LN2 pouring, you could use a phase change unit, conveniently in a case here http://www.ldcooling.com/shop/l/51-ld-pc-v10-phase-change.html

For a regular custom loop, if you have a reference card you can get GPU and CPU for 240 in the form of EK's fluid aluminium kit, for actual custom loops using copper expect that price to double or triple, my custom loop (including fans) came in around the £1400 mark.

Yea many can't seem to understand how I have almost always over $300 worth of just Fans in the Desktops I build; it adds up, and it's needed for higher-end configs.

[tacoshy]

push = the fans are mounted to push air through the radiator (in front of the radiator)
pull = the fans are mounted to pull air through the radiator (behind the radiator)
push-pull = the fans are mounted to "sandwich" the radiator to push and pull the air through it.

[Monk]

I'll add a note that you don't need push pull unless it's a really thick radiator, like 60-80mm and very high fin density.

^ This, and to further help to not need Push+Pull; try good quality fans like Corsair SP series, which provide better static pressure allowing it to better push through Rads or HDD Cages. As long as you don't have a physical blockage that is abnormal in the mix.

When I do builds with say Hyper212-EVO (which is alot over the years) when that CM Fan dies, I stick a single Corsair SP 120mm on there and it works wonders, it also lasts a very long time, unlike the CM fans.
