HBA cooling

I have LSI 2308-based HBA card in my home server and it's just running hot even these days and idle. The fact it's pretty much stuck against Intel X710 card that's also pretty hot doesn't help either.
Does anyone know about some sort of a PCI slot FAN bracket I could use to mount say, 92mm, FAN roughly over the HBA's heatsink? I found something from Akasa, but the FAN is mounted pretty much right at the back side of a case, and the heatsink is few cms further into the case, so it's not a solution.

I use these ones as you can slide the fan to a few different positions to suit your needs :)

Depending on how DIY you want to be, you can mount a fan right on the card (depending on which actual card you have of course). Here's an LSI 9207 (SAS2308) with a 40mm fan mounted with long screws replacing the original push pin heatsink mounting. Need to use care not to torque the screws too much, but it works pretty well. I have one on a 2008 based controller, and also the integrated SAS3008 controller on one of my Supermicro boards. On the supermicro board, the push pin hole pattern was wrong, so I used machine screws to "friction fit" screw down between the pins on the heatsink (the way the really old AMD coolers did).

A picture really explains it better than words. I had no pics of my own setup, so I used this one from here: Cooling Suggestions for LSI SAS card? (LSI 9207-8i)

Oh, Amazon is usually out of question since I don't live in the U.S. Also this bracket is to mount a fan horizontally, but I want it to blow directly on the HBA, so it should be vertical.

That would be last resort. 40mm FAN, that's like having an aeroplane fly next to you. Hell no :D
I'm thinking 80 or 92mm.

I use a Noctua just like what is shown in the picture (NF-A4x20 PWM). They don't move a ton of air like a 1U case fan does, so are pretty much totally silent (14.9db). I have mine set to 100% and can't hear it past a couple inches away, even with the cover off.

If the airflow is directed right on the heatsink you don't need a ton of it. Just enough to carry some heat away.

Mounting a 40mm fan like that caused lots of fan failures here as motors died from direct contact (heat) with the heatsink. You better mount a fan blowing air from the end of the card and out of the case. Some other parts of the card get some airflow as well.

The link is just an example as you can find those sorts of brackets all over Ebay/Alibaba/etc
I've found a 120mm or 140mm fan moves plenty of air, even in that orientation and is dead silent

Ebay is basically full of these

neither of which is what I'm looking for :(
The first one would be IF there was possibility to mount a fan further inside or away from the back side of a case.

I made use of 45mm sunon fan for cooling, consider also fc-2000-b, there is a version with automatic thermal control - I found this the best option because you are wasting slot next to the controller anyway - why not use it as an exhaust for hot air from the controller instead of spreading heat all around.
