Deepcool Gamer Storm Captain 240 EX CPU Cooler Review




From the moment we got the Deepcool Captain 240 EX out of the box, it’s been a process of taking the good with the bad. We’ve had great looks and nice braiding on most of the components but poor braiding on the fan hub, as well as the regrettable decision to use a plastic backplate which may or may not have been a factor of the installation issues I had.

The new fans are what the EX is all about and running near silent while being pushed to max RPM is a nice thing, even if a lot of the noise reduction is done through speed reduction. I would have liked to see these running just a little faster to get some better performance compared to the competition but when it came to overclocking at least the EX proved to be an improvement on the previous design.


Deepcool’s Captain 240 EX looks awesome in black with subtle red accents, and if you get a chance to see the white one it looks even better. It’s not just looks, but it is better than the previous non-EX version when you consider looks, cooling performance and noise, but there are just some areas that I think could have been improved further to make a truly outstanding product.


Thanks to Deepcool for sending their Gamer Storm Captain 240 EX in for review, it walks away with our Design Award as well as our Silver Award today.

  • Performance
  • Design
  • Value



- Gorgeous looks for both the black and white versions
- Reasonable cooling performance that it a step up from the previous generation
- Fair pricing in both UK and US
- Good quality braiding on hoses, fan and pump cables
- Near silent running while at max RPM for pump and fans


- Installation process is a challenge to perfect
- Some poor choices in design such as the fan hub braiding and plastic backplate

  1. I know this is an old review, but I am just now in the market and doing some research. In your section about hooking it all up you stated that the fan hub “that allows for the pump and all fans to be attached to the CPU fan header”. Did you plug in the pump header to the fan hub as well as the two fans and then plug the hub into the motherboard? I was under the impression that you should plug in the pump to one motherboard header and the fan hub to a 2nd header.

    I am not an expert on how this all works but the PWM feature allows for tuning up and down of fan RPMs to match CPU load through the CPU header. If the pump was attached to the hub would this not tune both the pump rpm and the fan rpm down as the same rate, thus having a doubling effect on the lose of cooling?

    Modern motherboards now have a PWM header for pump operation and a separate header for radiator fan PWN operation. These can be tuned in the BIOS and thus effect a better performance across the idle to load spectrum of operation.

    Again I am not a expert in CPU cooling. This is just my speculation on how this is supposed to work. I got the impression from how your review was written that this was not the case. If you could please set me straight I would appreciate it.

    • You are correct, by using the same hub as the fans, the pump would be dialled down which results in less liquid passing the copper heatplate per minute than if it was running at full speed and this would give reduced cooling. It’s not something to be worried about though, as if the CPU got ‘too hot’ according to the thermal profile then the voltage being fed to the fan hub would be increased and both the fans and the pump would speed up. You also get the extra benefit of a quieter pump at the same time as quieter fans, and the main reason for throttling at all is for better acoustics.
