Aio liquid cooler best as intake or exhaust?: buildapc – Reddit
Intake is better for the thing that is being cooled by the AIO. Not for the performance doesn’t degrade if it’s 2-3C higher (intake vs exhaust), as long as it’s below the throttling you will be replacing an actual intake fan (or multiple) with the AIO radiator assembly (most common scenario), you are both reducing the amount of air that’s being pulled into the case and you’re replacing what is left of it with warmer air. That will increase the ambient temperature of the performance, contrary to CPUs, is affected by the GPU temperature which is affected by the ambient temperature. Especially in NVIDIA cards because of how GPU boost ambient temperatures might cause semi passive component’s fans to spin when they otherwise wouldn’t. New graphics cards for instance generally don’t spin below 55C, with higher ambient temps you might exceed that, on big overclocks and on power thirsty CPUs there’s a big strain on the VRM components of the motherboard. Since you’re using an AIO, there won’t be any active cooling on those components and they’d be relying on the circulated air inside the case. Which with an AIO as an intake you’ve both reduced and increased its an FYI.
[SOLVED] – Setting AIO Pump Speed / Temp curve. | Tom’s Hardware Forum
[SOLVED] – Setting AIO Pump Speed / Temp curve. | Tom’s Hardware Forum
Mar 2, 2014
So i’m a new AIO user, just got Castle 360EX, i’m bit confused about setting pump speed. I m not able to set a stable pump speed curve for low/idle work loads.
I have 3700x and Gigabyte Aorus Elite x570, I’m using gigabyte SIV software to set fan and pump curve.
With Fans i have no issue.
Thing is when i set a temp/speed curve on pump, pump speed keeps changing every second because ryzen boosts higher / low workloads, i can’t get stable pump speed at idle or low workloads, it keeps on going up and down.
while gaming/productivity tasks it settles to a stable pump speed easily, it makes me skeptical at idle and lighter workloads that changing speed so fast might affect pump itself.
I tried to get a stable pump speed curve at idle temps but barely i got in a range of delta of 200-250 rpm
Here’s some data for reference:
Idle/Low work loads: 3. 6 – 4. 4 GHZ 44-60’C 1250 rpm -1550 rpm delta 300 rpm
Gaming /Productivity Loads: 4. 0-4. 3 GHZ 57-68’C 2000 rpm-2100 rpm
Whenever i reach closer to a stable pump speeds at low workloads curve ryzen starts boosting longer to make setting a failure.
Pump has min 800 rpm[30%] and max 2550 rpm[100%] pump speed,
Please suggest should i set fix pump speed like 50% or 60% or 70% or 100% etc for all time use and never bother changing it again.

Pumps should run at a constant speed all the time. On my custom loop I have it set to 85% because that is as fast as it will go without being audible. Many AIO’s can be run at 100% and still be inaudible.
Your radiator fan speeds should be tied to the fluid temp, or if that is not possible then tied to the processor temp.

Why not just leave it at 100%?
Does it usually affects pump life/efficiency in long run [let say within warranty period of 3 years]?
Are AIO’s are meant to run at 100% always?

leave it on auto all the time.
There’s no auto, How am i set it to auto? It’s connected via PWM so it works either:
-> with given profiles like: Quiet, Satandard, High Performance or Full Speed,
-> custom fan speed / temp curves
Thanks man, i will probably set it to 70% ~2050 RPM with fans on a cpu temp curve. I will leave it like that for eternity.
Just you know i was trying really hard this year to build a CLC myself, but you know, the thing that shall not be named got in the way and i didn’t get the parts i needed so i have to settle for an AIO.
Not that it works bad or anything, but i feel like being pushed back into the crowd again ever since i dropped the task to build a CLC. :/
It’s an AIO, the pump isn’t that powerful to begin with, so slowing it is just diminishing your cooling potential by lowering the already (very low) flow rate.
It’s not like a DDC or D5 pump which are many times more powerful.

What Is The Risk When Using An AIO For CPU Cooling?
Quick and Dirty Water Cooling | The Risk of Water Cooling | The Good PartFirst off, an AIO is short for “All In One”, which in this context refers to a liquid CPU AIO combines the parts necessary to liquid-cool your CPU into a pre-packaged solution that you bolt on in about 20 minutes. The AIO combines the water block, radiator, tubes, fans, fittings, and pump into 1 sleek package. A Quick Lesson On Water CoolingThe reservoir funnels cold water into the pump (generally directly below the reservoir). The reservoir helps during loop filling/draining, and thus while isn’t totally necessary, is extremely helpful. Large reservoirs can hold more water, which means less goofing around with a funnel and distilled pump moves the cold water (and water overall) into the water block for the heat (CPU), and out of the water CPU generates heat, which is conducted to the IHS (integrated heat spreader), or the shiny piece of metal with the CPU model written on heat is conducted to the water block which is laid on the IHS (there’s a thin layer of thermally conductive material between the IHS and water block, as the water block/IHS contact isn’t perfect) water block uses an array of extremely thin fins to increase the surface area from which the heat can dissipate, and water is run through those micro-fins to move the hot water away from the heat hot water goes to the radiator via the tubing, is run through the radiator fin array to dissipate the heat out of the loop fans on the radiator move the hot air away from the loop itself, and out of the now-cold water moves from the radiator back into the reservoir, and the cycle AIO simply compresses this loop into a much smaller package, and removes the large maintenance issue that you get with a custom the system above/below, the loop ran like thisRes>Pump>(Bottom Case Transfer Tube)>360 Radiator>GPU>CPU>240 Radiator>(Top Case Transfer Tube with Flow Meter)>Res>PumpThe Risk of AIOs (and Water Cooling overall)With water cooling, you are reliant on every part in the system working as it should, in order to have a functional cooling system. The blocks need to not clog, the radiators need to not leak, the fittings need to remain watertight, and the pump needs to remain any one of these things fail, you generally have a big problem pretty quick (overheating) means the heat isn’t moved away from the source, and the cold water isn’t moved in to absorb the heat. You generally have an automatic thermal shutdown in a few seconds when that happens. Not necessarily good for a production the radiator leaks, you’ll be losing coolant. While not an immediate issue on a big loop with a big reservoir, AIOs don’t have a reservoir, and thus a radiator leak is an issue. If the fittings leak, you have a geyser. Water cools only when it’s contained. Water and a powered up motherboard do not mix tually, water and electricity mix very well, but that’s not what you want. AIOs don’t have fittings, so to speak, but you get the Good Part! Reputable AIO manufacturers such as Fractal Design and EVGA tend to put lengthy warranties on their products, as they are that confident in their aren’t as big and bulky as their respective air brothers, and thus put less physical stress on the motherboard. All you have in the AIO is the pump head, soft tubes, and the radiator (and fans). No big monster metal air cooler!
