Is Open Hardware Monitor the only non-cost option that works with Aquasuite?

The reason I'm asking is that I've been having some intermittent trouble with it. I have 4 storage devices in my computer. One SSD with a static-reading temp sensor and three mechanical HDDs of various capacities. I have a fan in front of the hard drive cage whose speed is determined by the temperature of the drive that runs the hottest.

Problem is, every once in a while OHM reports HD1 (the hot drive) with HD0's temperature (a constant 30 deg C). This means that the HD cooling fan never spins up and the mechanical hard drives start getting very warm. The only solution that seems to work is a full system reboot. SpeedFan never confuses the HD numbers, so it doesn't appear to be a hardware reporting or Windows issue. Re-starting Aquasuite or the Aqua Computer Windows Service doesn't fix the issue. The problem seems to be specific to Open Hardware Monitor software. This is potentially dangerous as I don't always watch my temperatures. I have software that doesn't that for me.

I'm running the latest version of the Open Hardware Monitor software (0.51), but creator hasn't updated it in a while. Is there another free software option that works with Aquasuite's software sensors, or is my only other option ponying up $40 for AIDA64? That seems a pricey option just to get working sensor readings into Aquasuite.

The issue with that is that hard drive longevity increases if they're allowed to get a little warm, so the fan doesn't turn on until they warm up a bit. If I ran the fan constantly, even at it's lowest possible setting, the discs would take a long time to get up to temp if they ever got there at all.

Basically, it feels like I'd be engineering my way around a problem that shouldn't exist by doing that.

Yea, it's kind of an odd issue I suppose. The reported temp within OHM is correct when this happens if you look at device names, it's just that it reports HD0's temp in the slot that it normally uses for HD1. For the cost of free I suppose I can't complain, but I do wish temperature monitoring was a part of Aquasuite instead of requiring other programs.

Update and what I think will be my final solution for this.

The problem kept occurring at random, but I finally had a brain cell fire off an idea at me today.

Virtual sensors. I set a Virtual Sensor with all the hard drives in the system, and had it take the highest one. Even if the name/number they get reported as jumbles around, I'm only concerned with the highest one anyway. The only downside is that since I have 4 drives (SSD plus 3 HDD), I had to use two virtual sensor slots to pull it off. Thankfully, the software allows one virtual sensor to be used as reference in another virtual sensor.

There's no way to increase the number of input slots a virtual sensor uses for input, right? No way to make it look at the highest of 4 values?

A Yate Loon 120mm fan spinning at 200rpm keeps the drives at a very comfortable 35-38deg C. It spins up from there as needed if ambient starts getting toasty (which it does in the summer), keeping the things at 40-41 deg C or less. "Asthmatic ant" is a good way to describe a Yate Loon at 215 rpm, both in terms of airflow and noise production, but it's just enough to do what it needs to.
