Where a 240mm AIO fits
The MasterLiquid 240 Atmos White is a sensible upgrade from a stock or entry tower cooler for mainstream six- to eight-core chips such as a Core i5/i7 or Ryzen 5/7. A 240mm radiator fits far more cases than a 360mm, including many Micro-ATX builds with front or top mounts, so check your case lists 240mm support at the position you want. If you run a flagship Core i9 or Ryzen 9 under sustained all-core loads, a 360mm radiator will hold clocks more comfortably. The fans come pre-installed on the radiator, which saves a fiddly step during the build.
White build trade-offs
This is the white version, so the radiator, fans and pump housing suit a white or light-themed build; a black version is also made. The fans spin up to 2500rpm, which moves plenty of air but is audible at full speed, so set a sensible PWM fan curve in your BIOS or MasterCTRL. The pump top cover can be customised with 3D-printed designs and is made with recycled plastic. Both the pump and fans use 4-pin connectors, and the lighting is ARGB, so you need a 5V 3-pin ARGB header or controller to sync effects. Tube clips are included to keep the hoses tidy.
FEATURES:
- Patented dual-chamber pump design that directs flow to the CPU hot spot
- Pump top cover that can be swapped for 3D-printed designs
- Pre-installed 120mm ARGB PWM fans with loop dynamic bearings
- ARGB lighting, controllable through MasterCTRL software
- Recycled plastic pump cover and reduced packaging

Questions
Before you buy
Is it in stock, and when will it ship?
Yes - this one is in stock. Order before 12:00 on a working day and it ships the same day; after that it goes out the next working day. We are open 09:00 to 16:30, Monday to Friday, so an order placed over a weekend or a public holiday ships on the next working day.
What does delivery cost, and how long does it take?
We deliver by courier anywhere in South Africa, and delivery is R180 on orders under R2 500 and free on orders of R2 500 or more. It takes 1-3 working days to Johannesburg, Pretoria, Cape Town, Durban and areas within 100km of them, and 2-4 working days to areas more than 100km from a major centre, counted from the day the order is dispatched. Need it sooner? Express delivery is 1-2 working days for R210, or R150 on orders of R2 500 or more - choose it at checkout. We do not ship outside South Africa.
Can I collect instead of having it delivered?
Yes. Collection is from 11 Voortrekker Avenue, Edenvale, Gauteng, by arrangement - message us first so we can have the order picked and waiting. We are open 09:00 to 16:30, Monday to Friday.
What warranty does it carry, and how do I claim?
The warranty period for this product is listed at the end of the Specifications section above. Claims go through us, not the manufacturer - contact us with your order number and a description of the fault and we will handle it from there. Separately from any warranty, the Consumer Protection Act gives you six months from delivery to return goods that are defective, unsafe or not fit for their intended purpose.
What if I change my mind?
You have 14 days from delivery to change your mind - longer than the seven days the Electronic Communications and Transactions Act requires. The item needs to be unused and in its original packaging, and we pay the return shipping. Refunds go back to the payment method you used, within 30 days of the return reaching us.
How can I pay?
Payments are processed by Stitch. At the last step of checkout you are taken to Stitch’s secure page to pay, and brought back here once it is done. Your card details are entered on Stitch’s secure, PCI-compliant page and never touch our systems.
