Computer build

  • Question
  • Updated 1 year ago
I am in the process of a New Computer build for my station. I am tossed between a Air Cooler for my CPU or a Water Cooler system. Has anyone had experience with either? And my main concern is.... a Water cooled system has a small pump as well as a fan or two. Has the pump ever caused any noise issues with the receiver of the Flex Radio. I am going to start building this over the weekend and was unsure of which direction to go.... so I ordered each option system knowing I could send one back if I choose to. As I am contiplating which to use this question of receiver noise came to mind! Your input would be greatly appreciated!

I've used both and they each have their advantages and disadvantages. At present I have been running the Corsair H50 for about 8 years now with no issues. It is a closed loop liquid cooling system. Works great unless I really go crazy with the over clocking. I see/hear no noise from it on the Flex.

Edit: Forgot to add that I run 2 fans on each side of the radiator in a push pull configuration.

Jeff, had the same bug a couple of years ago and settled on several 6-inch 12V fans — was a deal from Amazon. Created a small gale through a half-rack. Then I realized I have only rarely caused the Flex fans or my linear amp fans to trigger. I’d go smaller. Maybe put a switch on them to keep them off routinely. My two cents.

If you don't overclock your system to get max performance, go with an air cooler
as it will be more reliable and sufficient for a normal system

There is little need for any of that CPU power level.  A 14V fanless i5 or i7 will run everything needed, unless you are including a 5000/3000 in the mix.

Jeff- As a Builder of systems and hardware guy for over 25 years, I currently use both, a Fan cooler for my CPU (depending on the fan cooler I would suggest replacing any included stock fan ) with an good aftermarket brand . I do use a water cooler on my Video card, as I push it pretty hard at times with video rendering gaming etc. XZXT Kraken is the block I use for video cooling, and a Noctua air cooler for the CPU, haven't had any noise issues, However the biggest noise maker for a computer is the power supply being used, watch these especially lower end units I have come across several which make a plasma TV look like your best friend. Next are controllers for led lighting systems a few of them produce RFI hash as well.
