The Flydigi BS1 cooler actually delivers.

Blog/Article

I'll start with answering a frequently asked and incorrectly answered question.

Do laptop coolers work?:
The short answer is yes, BUT it has to be the right cooler, or laptop set up.

Typical coolers have 5v axial fans (the typical PC fan style), these are pretty lame for 2 reasons.
1. 5v fans barely move any air at all due to not spinning very fast.
2. Usually a cheap design and have even less static pressure than the typical PC fan.
These coolers may give a little assistance but nothing special, there are some better engineered ones that may help more on a laptop that can breathe easier. Think of this as blowing through a sponge filter vs blowing through a larger holed mesh, which will get more air through it at the same force.

Centrifugal blower however have a lot of static pressure and can easily force more air through the fans and chassis. The trade off however is noise, they normally make a bit of a racket at high RPMs.

So take something like a GT500 /GT600 or a Llano V12 or any version of the Llano, these coolers have immense static pressure and can easily double( and more) the airflow through your heatsinks. Only even at half speed, these things really are loud. You need a good headset to overcome the din they make.

Enter the Flydigi BS1.

Same concept as it's other brothers, a high speed centrifugal fan and a memory foam gasket to ensure the air is channelled through the laptop. Key difference is the intake is channelled and the exhaust has finned chambers. This stops vortexing and muffles the sound quite dramatically in comparison to the GT and V style coolers.



I did a little short testing session on my Legion Pro 7i.
TIMs are:
Conductonaut Extreme on the i9 (undervolted and downclocked)
Lenovo LM from the kit on the 4090 (voltage capped at 0.900mv with a +300 OC
Fehonda LTP81 on the VRAM and VRMs.

I also have a modified secondary chassis bottom that I made for the use of my custom cooler with 3 T30s all capable of full speeds. They're filtered so nothing can get into the laptop either. This set up is designed to achieve more airflow to the fans, over the VC itself and also to cool the RAM.

Testing was quite brief, I do not have a load of screenshots since you can't actually see the coolers to know I'm being honest, but hopefully my other posts with proof will garner me the benefit of the doubt. Anyway, I did a few runs of CB23 with my cooler on full, the T30s on the 3000rpm advanced mode, a few on the BS1 on "Overclocking" mode, then played about an hour of Diablo 4 on each cooler too.

The BS1 edges a win by about 3c on the CPU and the GPU was about equal, but the scenes played and such aren't identical so that could come down to scenario. However loading screens and CBR23 is the same. D4 CPU temps were 64c peak on the T30s and 60c peak on the BS1. GPU temps were 52c T30s and 53c BS1. My RAM was cooler on the T30s, but that's because of generalised airflow through the chassis compared to the BS1's targeted.

Noise levels though? The BS1 wins.
3 T30's even at full song were still quieter than my modified (to be quieter) GT500, and the BS1 is even quieter still. In all honesty you would not need to run the BS1 at full speed to get a substantial reduction in temperatures. Setting 2 (of 4 in total) is about on par with the laptop fans running and the airflow is about what the laptop fans can shift at full speed. I also intend on testing this cooler on my 15ACH6H since I know roughly that can get about 70c on the CPU in game and I believe 60c HS on the GPU. I'll do some with and without for that one.

So it has the right fan type, it's actually quiet as well as genuinely performant, the last important question is... How much?
Well, that depends where you buy it. It's about £100 on Amazon, yet I bought mine for £60 on Aliexpress, it took a couple of weeks to arrive, but still. £40 saving is no small amount. I can share the vendor if anyone wants a trusted seller on there should this tickle your fancy. It does require a 20w USB C charger to run at max power so if you don't have a newish fast charger you may need one.

Do not take my -3c as that will be all it manages. Take into account my machine is modified and sits on a custom cooler. A stock machine will easy see a minimum of 10c drop in temps over stock. or if not you'll likely see much higher wattages before throttling.

Any questions feel free to ask.
I didn't post links because the website is Chinese and links to Amazon, I didn't link Aliexpress because I'm not a salesman, but I will give it if requested.

TL:DR:
Flydigi BS1 go BRRR, will make your laptop significantly cooler (-10c +) without a lot of noise and if bought from the right place it is not only quieter than it's competitors, it's cheaper too.
Needs a 20w USB C charger to run full beans.
