Corsair H Single Series

[Dawelio]

Heya guys,

Probably a stupid and retarded thread and questions, for most of you... But I've been wondering something here and can't seem to really come up with it, or I just down right suck at finding the correct information :huh:...

But what is the difference, if there are any, in terms of the pumps on Corsair's older models, round pumps, in comparison to their newer/updated, more square shaped pumps?

Also, and this is kinda my question with this thread, are there any huge differences between thickness in the rads, I mean, for real?... Like comparing the thinner H60 with the thicker H80?...

Thanks,
Chrazey

Afaik, it's not necessarily older/worse but just... different pumps. Due to the fact that Corsair seems to use two different OEMs for their liquid coolers (which imo is a smart move cause it makes the brands compete against each other to make a better product for Corsair while they can't ask just any price they want).

For instance, the H105 is quite recent but still features the classic Asetek style round pump. For all the other recent products they seem to have used the square CoolIt design.

Even in the Coolit designs there are differences though. The H100i and H80i have a variable pump speed with a maximum of iirc ~2000 RPM. The H60 2013 Edition looks the same, but the pump does ~4000 RPM and you cannot officially control it. Whether that means it's a different, cheaper (slightly worse) pump, or them trying to compensate for the single slim rad while still keeping decent temperatures, I don't know.

One thing no reviewer has ever done that I would like to see is to disassemble them and look at the GPH that these type pumps put out. That would not be hard to measure. A head pressure reading would be nice, but harder to achieve.

But how much difference does a slim rad (H60) do in comparison to it's thicker brother (H80) in terms of temperatures. Do you guys think?... Is it a huge one or a small one, that doesn't really matter in real life?.

But I agree with you Kong, it would definitely be interesting to see those results

Just search for the reviews that compare them to other units. A thicker rad will always run cooler than a thin rad of the same size. An H80 is slightly warmer than an H100 but cooler than an H60.

Aye, just check out the review. In theory, the H100(i) has double the surface area of an H60, but it does not mean that it performs as well. There are many more factors like the speed that the water flows at, which is much higher on the H60 due to the 4000RPM pump, which also means that it's a little louder despite having only one fan.

Thanks dude, keep forgetting to look if OC3D has made any reviews of a special product. Thanks!

Yeah, that's true. So I know you've mentioned it before, but can't you turn that speed down though?... Or is the H75 better than the H60 in terms of the pump speed etc you think? Unless you can turn down the speed of course.

The difference between 2000 and 4000RPM (assuming it's the same pump) isn't going to affect temperatures in such a low restriction small loop. Unlike fan speed the returns of increasing pump speed are not linear, once the flow rate is high enough there are no substantial gains. If they've just used a terrible design and made it spin really fast then I would probably avoid it. The H75/H105 sound absolutely awful in my opinion, the original H80i/H100i is the most refined and best all round product to my eyes/ears.

Radiator thickness is another quite negligible factor and there are a lot of other factors which will effect the efficiency of a radiator such as fin density, tube size, tube material, fin material, fin shape, amount of passes... all of which make a difference and can give one particular radiator an edge when appropriately paired with a certain set of fans at a certain RPM. It's a rare for a radiator to be universally better at everything, some will just shine with low RPM fans. And at they end of the day they all just amount to relatively small differences in efficiency. The frontal area and flow rate of air are the main factors which influence how much heat can be dissipated for a given difference in temperature.
