Today I wrote an email to Aqua Computer explaining my disappointment on major shortcomings on the aquasuite software controlling an aquaero I just recently purchased. As I think these points need to get as much attention as possible I decided to copy-paste my mail here, to have other people express their support for these features and for also have their say.

Hi!
Over the weekend I got the time to familiarize myself with the aquasuite software. Setting up the hardware for my new system my first impressions were no short of being enthusiastically impressed with my newly purchased aquaero 6 Pro. But unfortunately as I got to set up the aquasuite software to control all the fans in my system I was in for a near total let down. There are a couple of things. The first one is that you can not assign multiple curve controllers to one and same fan output. The second one is that you can only have a total of four curve controllers.

Now if this is not just due to me obviously not yet knowing to how to use the software properly but an implemented limitation, the fact that you can have only one curve controller per output is an absolutely essential and basic flaw. Also the number of simultaneous present curve controllers is way, way too low. It should be at least around fifteen, preferably much more.

Allow me to try to explain my point of view. When the usual situation is that you have at least several components inside your computer case that generates a large amount of heat, CPU, GPU, certain motherboard hot spots and other possible sources and you have a fan, possibly several, connected to a same single output on aquaero in such a configuration, that this or these fans provide or affect on the cooling of more than one of these parts, then assigning only a one curve controller that is defined by only a one temperature sensor to this particular output will leave these fans completely unaware of the other critical temperatures of other components they should know about and to spin up and cool accordingly when they heat up. As of current you have to make the daunting choice which one(s) you think is less worse to possibly be subjected to heat generated and not cooled when appropriate. To manage things properly in addition to having the ability to assign more curve controllers to a same output you could need at least quadruple the amount of curve controllers you can currently create in a large case with many fans.

I come from using SpeedFan. I've been using that great free software for some time before I decided to update my system and at the same purchase aquaero 6 Pro. Now unfortunately these elementary deficiencies I'm facing with the aquasuite are very nearly a deal breaker for me and I have seriously been thinking about returning the product. The reason why I brought up SpeedFan is that it is a perfect example how the aquasuite should work and then top it in many ways - this is what would happen if these two things I'm writing here about were fixed. In SpeedFan you can assign unlimited (to my better knowledge) number of curve controllers to one fan output and then select to have it operate with the max speed indicated by any given curve created or have it operate with the sum of the speeds of the curves. I also think there is no limit on the number of concurrent curves. Why should there be? I'd be willing to say it to be a reasonable estimate that they won't reserve so much resources that that number should be artificially limited. Third important thing I'm seeing missing in aquasuite is a hysteresis option for the controllers (for explanation see picture below). I'm sure you could very well be familiar with SpeedFan, but I'll put a link to a picture I created just in case right down here to illustrate what I'm talking about:

As customer who likes to make a difference and be a part in helping to drive a product to develop into an even better I would be wonderfully thrilled to hear that you would be ready to give these revision propositions a real consideration in your forthcoming program updates. Hearing this would also help me personally in decision keeping the product for now and have hope that someday these shortcomings will be fixed and that there's an absolutely awesome product to be owned and to told your friends and other forum members on the Internet about!

I think that you need to look at the Virtual temperature sensors in Aquasuite.

Remember that even though you setup the Curve Controllers in Aquasuite, they are actually implemented in the Aquaero itself, and operate when Aquasuite is not running.

The Aquaero has memory limitations that would prevent 15 Curve Controllers.

After using the Aquaero6 XT in two of my builds over the past year I find that there is nothing on the market that has all the capabilities of the Aquaero/Aquasuite combination.

I don’t know the physical memory size on aquaero, but when talking about storage memory limitations I would estimate you could fit roughly a hundred power/temperature curves into a single megabit. RAM shouldn’t be an issue either, as you look at memory usage of an active running SpeedFan and it’s in a much more complicated OS environment. I should note that I’m not a coder and mainly using common sense.

I had yet to look at the virtual temperature sensors. It looks like this might partially settle the lack of features I’m describing. I’ll probably be a little happier now with this, than how it looked for a while. Thanks for pointing me to right direction!

I now tried to set the fans to behave as I want them to to best of my abilities by taking advantage of the virtual sensors wa3pnt pointed. They did provide a passable solutions that will have to suffice in lack of a better one, but only with the use of the offsets to their maximum limits to different temperature sensors. This also almost turned out to be an unusable solution because the limited +-10 offset boundaries weren’t quite enough for balancing the control for desired behavior from each sensor when using the “highest temperature” mode. This garbles the temperature readings for display purposes, but there is no choice.

I almost get the impression that this has been designed for users with their whole system behind one or two liquid cooled loop where much is stacked together temperature and cooling wise, neglecting users with air cooled systems, especially more advanced ones. Aqua Computer needs to get these few basic stuffs fixed. Like I said we’d then have an awesome product.

SpeedFan has its issues, too. Those issues are the reason why I was looking for more solid solution. For one with SpeedFan it’s throwing dice what options you motherboard happens to provide for fan control on hardware level and for second how well SpeedFan happens to support that particular motherboard. Motherboard fan outputs are also more limited than standalone solutions - in numbers and for example often having a combined 1 amp current limit. I also liked the idea of software independent cooling system.

aquaero / aquasuite is so close to having the ultimate solution also for air coolers, that it is goofy to see this product not being utilized to its fullest potential with seemingly minor software corrections, for the possibility of increasing the customer pool.
