Do you know if the Corsair iCUE H150i cooler comes with thermal paste included?

[jordiqui]

I understand that for many people it is a hassle to set up a liquid configuration by parts. But a good block, radiator and pump and have it installed if you don't know how to do it. But I think it is better if your pocket allows it. What I don't know is what performance these kits that I see so much in the ads have reached.

[defaultuser]

@jordiqui Well yes, with a custom you can get what you want, but what is achieved with these I don't see either, people are not rigorous.

Looking and imagining that everything is compatible, then the price goes up. But not much more than a complete kit from the ones sold by X brands.

Do you know what I think about that? The D5 is a marvel but it provides more flow than the block can handle, so it has to be PWM to force it only when necessary, or if not, you'd better get an increased version of the DDC that gives the same pressure but with a flow rate more suited to those blocks. I'm speaking without having tried it, but I had an even lower one and if the flow is excessive and the pump isn't especially good at pressure, it will end up doing ricochets, water hammer in bursts due to returns in the pump body. I would have to try it myself to be sure, but I already told you that there are very suitable DDC variants.

Then you can use wider tubing (with its fittings, but for 1/4" thread of course) and the restriction to a D5 is only in the mouths of the block and the radiator.

Then there's the radiator, the most important part of the triangle. Once we've decided to go custom, let's put what's necessary so that the water barely exceeds room temperature, and with low noise. I say what's necessary to leave it to the discretion of each one, since it can be achieved in different ways, besides the choice of the radiator(s), you can put other fans, even of a different size, and more things.

I mentioned a triangle, right? It's about a radiator capable of reducing water to ambient temperature, a block capable of transmitting all possible heat to the water (one that allows good flow is one of the requirements), and finally a pump that, beyond its specifications on paper, produces a notable effective flow (let's say a D5 is perfect).

The weak point of this triangle is the radiator, it's simple; water has a great absorption capacity, with a large block that allows flow, you don't need many frills to evacuate the heat, then the radiator again exchanges very easily with the water, and if the block and pump are oversized, then it's fine.
But what about the radiator? it turns out that the most inefficient part is the delivery of that heat to the air (the air is very bad at admitting and delivering heat and water is very good), and it is precisely this part where you can really get the most out of a liquid compared to a pipe solution, that is, in addition to removing heat with water that absorbs much more watts, then you take that water wherever you want and you have space to apply what's necessary to keep the water cold despite long benches and heated rooms.

For me, a real custom liquid is to keep the CPU die well below 40ºC in the middle of August without air conditioning and passing stress tests, but without airplane noise, or none if possible.

The AIOs (which I haven't had the pleasure of trying), will improve air solutions a little, they don't have complications and are ready-to-use products (screw and use), you can improve them simply by modifying the ventilation (in different ways), they leave you free space to put direct ventilation to the VRMs, they allow you to use narrower cases, they should make less noise for the same result.
etc etc, but they use little flow for a small block (the mass of the block should exceed the CPU die's mass by a good margin instead of being close) and the radiator doesn't stand out either.

All this breakdown refers to assembling a custom liquid that really takes advantage of the full potential of water cooling, and it doesn't intend to discredit AIOs, surely Corsair has developed their products conscientiously, but all adhere to physical limitations of a common concept for everyone, and their objectives must only be to slightly outperform the competition and keep the CPU just below its maximums, and things will continue to be like this as long as they remain limited by the assumed concepts and as long as no one unseats them from the throne.

AIOs are not bad, they are practical for those who have a high-end CPU and don't want to see it hovering around maximum temperatures, and they are not so expensive if you go for a simple model without frills, but they don't melt air coolers or anything like that, for that or to do OC under conditions, they are not the best option, and following custom tutorials to the letter is not either.

@jordiqui I don't know if you're making the shopping list but you're already making me envious...
If you get into this, look at the radiator thing more calmly, two in parallel, some monsters of those super thick ones that there were, don't just look at it because it's the bottleneck of your setup, and with those components you already have a top refrigeration, you would only need to optimize the heat evacuation to the air.

[Clipper]

@defaultuser I agree on certain points and disagree on others...
An R.L type corsair will yield more than a normal heatsink for the simple fact that it has greater surface area and will be better located than a "normal" heatsink
But.... That zero maintenance has its cons.
For mine in particular, I think the liquid can't be changed, and I don't think it will maintain its properties over time.
If the pump dies for X reason... Game over.
It's clear that a custom will yield more... But it's three or four times more expensive.
The D5 alone eats up 50% of the budget.. then add a decent block and a decent radiator and you're in the 400s and you still have the reservoir, fans and tubes.
Regards
P.d
I also tell you that if in 6 months a vein swells up on me...
I'll make a custom tower in iron and glass and put a custom loop in it, making the water blocks myself (CPU, GPU and M2)
Regards

Yes, of course, but how much extra cost is justified is a matter of the other advantages too, because the extra performance alone is not enough.

Tell us what temperatures you have when doing what... etc. that's what we need more of, precise info on how it performs, first-hand precise info, what we were saying..

@clipper said in Do you know if the Corsair iCUE H150i cooling system includes thermal paste?:

For my specific one, I don't think the liquid can be changed, and over time I don't think it will maintain its properties.
If the pump dies for X reason... It's done for.

You see, an advantage on one hand and a disadvantage on the other.
Not being dismountable is better for safety, it's "anti-hands" fool-proof as they used to say, but of course it's a handicap for others.
In theory, they should be using as much stable liquids as possible other than water, with characteristics that make filtration, evaporation, degradation, and expansion difficult, that's what I suppose, is done in other different applications.
What usually affects this issue is the temperature at which the AIO lives, of course.
The pump shouldn't fail you, it has no mechanisms or wear (virtually), but its useful life also depends on the temperature. In submerged pumps that are normal but not special, they recommend not exceeding 30ºC in the water, in these ones more will be admitted but having the system always rather hot can indeed break the pump when certain limits are reached.

In short, the cooler the better.

@clipper said in Do you know if the Corsair iCUE H150i cooling system includes thermal paste?:

You don't need such elitist material to get good results.
As long as the flow doesn't slack off and the water/air exchange reaches the desired efficiency, most of the possible performance will be achieved.

@jordiqui In reality, pumps of certain pressure are used because the circuit is restrictive, mainly the blocks.
For example, to cool only the micro, if we used a loop that was a little less restrictive, any pump would do, even those for 600L aquariums.
The pumps used give a little more pressure, thus producing an adequate flow despite the circuit restriction, but that doesn't mean that more pressure is better, when an adequate flow is already flowing, the benefits of jet effects and similar are small, and are negligible compared to the prejudice that it supposes to restrict the flow.
We must also remember unnecessary costs, the electrical consumption.

I would have to seriously look into it (if I remember correctly you have a tutorial on this topic), to find a balance. But there are more specialized stores, I imagine. Before it was cool... and another one if I remember correctly.

@defaultuser This week I'm on vacation and I hope to do all the pending tasks (which are not a few )
As for the custom ones, it's not about being elitist, it's just that anything is worth a fortune for what it is...
A bomb with two pieces of delrim and acrylic tube and two toric seals is not less than 140€ the CPU blocks idem.
I bought strawberries with a diameter of 1 mm and a 10 mm cut for electrolytic engraving and they were not even 20 euros.
A 5 mm diameter mill I don't think it's worth much more (the smaller the more expensive) the copper would have to check the price but it wasn't very expensive (in scrap) so I don't know where they get the prices of the blocks from.
That said, the tapping screws did "bite" a little.
I can understand the prices of the GPU blocks because there are 200 models, but the CPU ones are standard.

Out of curiosity, I'm looking at the D5 "bald" pump and I can't quite understand how it works.
I've had an aquarium and the pump had an inlet and outlet... on the D5 I can only see a central hole.

[defaultuser]

@clipper said in Do you know if the Corsair iCUE H150i cooler comes with thermal paste included?:

That's the fault of the pump and reservoir in one fashion, before you could get the D5 loose with a very standard base for under 50 euros and if you looked hard sometimes even cheaper.

@clipper said in Do you know if the Corsair iCUE H150i cooler comes with thermal paste included?:

I only see a central hole in the D5.

Are you not looking at one that comes without a base so that you can add the reservoir of your choice? in that case it comes without a head or threads and what you see is the internal turbine and the motor block.

Is it reliable to buy from here? I know people who have bought bikes (replicas at a really outrageous price. Another thing is that on the first descent the frame broke), but with computer components it is, I insist, reliable?

[Clipper]

@jordiqui
On a bike I can tell you that I've had a 29" carbon frame for years and no problem.
Also handlebars and saddle.
And on the skinny stem and saddle.
In computer components, I haven't bought anything.
I can also tell you that recently my boss spent 8000€ on a Chinese carpentry machine (a mortising machine) bought by a well-known Spanish company that verifies them and puts their brand on them, and it's from PM costing half of a German brand.
The Chinese are no longer stupid, they know they can produce the same and cheaper, but in certain things I personally don't take a chance.
A water pump I don't think will cause problems, a radiator I would think about it (for performance)
The last thing we at work got was a sound suppressor for a cal.4.5 rifle for a buddy.
He's delighted.
That said, they sell it as a motorcycle filter

That's the crux of the matter, comrades. Several brands have emerged that offer products at decent prices that seem perfectly suitable at first glance, but since they come from there and are not from brands with an established reputation... well, they give a lot of creeps, and as we're talking about liquid cooling, creeps x3.

Personally, as I deal with machines, if I had the budget to take a chance, I would buy it and run my own audit and quality control before putting it to use, at the risk of messing it up because my audit would void the warranty in some cases.
If that weren't the case, I don't know what I would do. I would try it because it could be very worthwhile. In a block, not much is needed to make it reliable, and in the pumps, there will be some that were already manufactured for other brands and use a core design that is already a good product.
The o-rings and closures are a bit delicate and precise, but not too much so, and if done properly, it should come out perfect.

We would have to test and analyze them, and get information from people who have used them or researched the brands.
It could be very interesting, but not with our eyes closed.

If you're looking at blocks, it's better to go for copies of known models, because some have a bad design of the acrylic part that affects the overall solidity.
There are some blocks where I would say no way, and others that could be just as good or almost.

[defaultuser]

@clipper
That's what happens, they already have good engineering for a long time, and so on the one hand they produce articles of their own brand that compete with others.
They also have producers without their own brand (a lot) that produced for established brands and this has filtered competition and know-how over time, causing them to now have a lot of specialized and up-to-date industry, and although of low level they participate in very valid final products.

The bad part is that at the same time there are also many initiatives at a very low level that put on the market final products with good appearance but with terrible engineering.
And like the marketplace pages these do not filter anything in this sense, so you have everything together and mixed up.

From what I have seen sometimes, I am convinced that there are perfectly valid articles and very competitive in price, but see who is going to corroborate their qualities, because from a photo we can say little.
