Custom waterloop GPU

Yea D5's are not stronger, they have much less head pressure. As I linked before you can get a DDC 3.25 for 70 euro and add to it any reservoir like for ex the Bylski tube res for 30 euro. That's all that's needed on a basic level. I don't really use combo top/res setups cuz they add noise by coupling the DDC pump to the res, which gets mounted to case which then transfers vibrations to case.


In my personal setups I always go for the Swifdtech MCP-35x pump because it uses Swiftech's superior pump top. I then add a heatsink housing to it and add whatever reservoir to it. For ex below, my kids loop. 35x pump+heatsink housing mated to ek res x2. In the above example to your question of what pump setup it'd be Laing 3.25+Bylski tube reservoir, that would be a basic setup that achieves 95% of the same performance. If I was on a budget I would go that route, if I had more budget I'd add better top and a heatsink housing.

I'll add a pic of my setup until recently which is again 35x+singularity overpriced reservoir plus heatsink housing. I'll use combo top/res setups from time to time but generally prefer to use them seperately.

Thanks this combo is not much more expensive but will require additional tubing... is the pump also fitting in this alphacool reservoir top?


Or


This would reduce the tubes / connections right?

I'd avoid both those setups, tiny reservoirs suck.

250ml is too little? Can you recommend then a top reservoir? I want to keep it simple for me and have less tubes if possible :) I plan to mount it with rubber screws/washers so I dumpen the vibrations anyways

The shape of the res matters. It's all you, you'll learn eventually.

Sorry I don't get cryptic messages :D are you saying cylindrical reservoirs are better? So I can use something like this then:

I use 250ml tubes they aren't ideal but just fine if that's all the room you have.

I was under the impression that tank size does not really matter... why would you need more than 250ml?

Huh?? The water is the thermal mass of the loop. The more water there is the longer it takes to heat up and conversely the longer it takes to drop. The more water there is the less susceptible the loop is to temp fluctuations.

Hi,
Larger can mix fluid more
Cooler tank outlet fluid verses hotter inlet fluid
Typically oulet goes from the bottom of the reservoir and inlet to the tank comes from the top.
Fluid does equalize just a matter of what is the fluid temperature after that if there is a problem or not.

You are making my point. Why do I care if my loop gets steady state after 3, 5 or 10 minutes? The end result is the same and the temperature difference should be negligible
 
Some people like to ask for advice then go on to continue making all their own choices regardless of the advice given.
I lol'd but you're dead on.

Dude I'm trying to have a discussion here and understand the rationale behind things and not be blindly force fed. If I read online plenty of sources say "reservoir is for refill and keeping bubbles only and size doesn't matter. Get one that fits in your case." And it makes sense from physics POV.... I can't easily fit a 250mm tube in my case as I also have 3.5" HDDs and 5.25" drive. The 5.25" I can probably remove and use it with external enclosure when needed but I would do that just because
 
Ideally you want a res thats easy to fit and and easy to fill. Thats essentially all you need. Your right in assuming that size doesnt really matter for the most part in helping to cool your components once equalibrium has been reached. Having a larger res makes temp spikes much less extreme and less noticeable. Which helps keep your pwm pump and fan settings from revving up and down.
The loop will naturally bleed itself for the most part in time(usually 24hrs). With a little help from you in the way of rocking and tilting it can be sped up but with a gpu only loop bleeding will be simplified. If space is at a premium i would go with a pump/res combo. A ddc combo takes up less space but can be loud. A d5 combo takes up slightly more but generally makes less noise. Compression fittings look nice but barbs and hose clamps are cheap and bulletproof.
Hwlabs rads are an excellent investment being that they perform at the top of every segment. Whether you go with gts/gtx/sr2 or gtr you simply need pair them with the appropriate fans and they will cool your loop better than or equal to anything else available today.
Tubing is not created equal despite what some may say and no they arent all made by the same place. The quality companies make their own and have closely guarded formulations they stand by with guarantees of satisfaction. Many cheap tubings will leech plasticizers into your loop leaving white powder on your blocks and pump. Others get brittle and others have color fade or change colors completely. Dont ever go with cheaper can be just as good options. Its the least expensive part of your loop so theres little need to cheap out. I highly recommend primochills primoflex advanced lrt. Ive used it in more builds than i can count and never had an issue with it. A note that makes matching tubing to fittings easier is- the fittings outside diameter has to match he tubings inside diameter.
So 3/8in. fittings to 3/8in ID x 5/8in OD tubing.

Investing in wcing is no different than buying any other quality tool you plan on using every day. Buy wisely.

Sorry for the wall of text.
 
After a deep research i found where to buy Primochills Primoflex advanced LTR: https://keepingit.cool/resellers i always bought it from EKWB but they stopped selling it.
Going to order 2 meter from the Netherlands reseller

Of course I am. Still mods out there that take reports on me seriously though.

Even when you're right, stating the facts to someone who doesn't want to hear it, on a public forum, is apparently trolling. Lol. Acting like I went to their house, knocked on their door, barged my way in and offered unsolicited advice lmao. By opening a public debate you open the subject to criticism in addition to praise, this is not a difficult concept.

OP will continue waiting for someone who has the same opinions as him to post, then continue with his original plan of doing what he wants to do, validated now. He's not here for advice, he's here to be reassured.

I you are implying I reported or complained about you or anyone else's feedback I did not. As you can see in multiple posts I welcome the discussion. I changed the initial plan on hoses, pump, radiator and pretty much everything on the loop except reservoir at the moment.

It's easy to tell hey just buy the best and most expensive thing but plenty of people drive a fiat and not Mercedes and have a B550 board and not a X570 Crosshair and go along fine. When people ask help for build, we tend aim for a certain budget and link components, reviews and explain why. I don't get why asking to elaborate a certain statement is seen as such an issue

As has been stated, more often than not custom water looping your system is the wrong approach if budget is a priority. Myself and others have told you to look at alternative solutions that may not be as pretty but achieve the same goals while being budget friendly.

People also have a time budget, so if as a newbie, you request advice on a topic, get solid advice, then go on to question every part of that advice while stubbornly sticking to your original preferences, most people won't bother to keep helping you.

Remember this is a public forum, filled with tech heads who more often than not, earn upwards of $100p/h or equivalent. They may not see the attraction of writing a referenced essay on every question you have.

You made your point after your first post. Repeating the same opinion in different ways does nothing to further the OPs discussion. It simply makes you look as if you are single mindedly ignoring the OPs initial post to argue a point he has no interest in. Hes simply asking for advice in building his first custom loop.

We get it. You think he should go with a hsf or aio. He disagrees and is going to follow thru with his original idea. Hes asking for advice in this very specific, very easy to understand endeavor not opinions in something he has no interest in. He obviously has experience in other forms of cooling. Why is this such a difficult concept for you to accept?

I have, alongside several other people, if you bother to read the thread, offered solutions that are still going with custom watercooling, which the OP has again ignored or questioned.
 
Hi,
Doesn't matter what size the reservoir is just make sure it has or you can use a D5 pump.

Filling and getting all the air out of a loop can be pretty tough
If you can't run a pump 100% because it's too noisy, you picked the wrong pump and or used way too many 90 degree fittings or both.

With the right pump you shouldn't need to run it at 100%. A typical D5 pump will achieve around 14-1500L/H flow rate, which is massive overkill for the 8-12mm internal diameter plumbing custom loops use, in all but the most extreme of circumstances. The temperature difference from running at 700 for example compared to 1500L/H in a typical 4-500W thermal load situation is less than 1 degree celcius. Look elsewhere for cooling bottlenecks such as IHS/TIM, radiator volume, coolant capacity/type, material W/MK rating/thermal conductivity before turning to a ridiculous flow rate to squeeze more cooling.

True.

Had a VPP655 at 3000rpm moving 7+ liters of water

Exactly, and why would you tout running something at 100% as being a positive? The MTBF numbers are typically generated at 80 or 100%, obviously running hardware at less than it's maximum output will typically result in exponentially longer lifetime.
