Arctic Freezer 33 eSports ONE CPU Air Cooler Review

The Arctic Freezer 33 eSports ONE is a CPU air cooler that packs some very healthy stats into what is a diminutive package if space is of a concern. Its price is also diminutive at only $30. The Freezer 33 touts a thermal coating that creates "micro-turbulences" in order to give it optimised heat-dissipation and increased cooling performance.

Introduction

Since 2001 the Swiss company ARCTIC has been developing quiet and powerful cooling solutions for desktop PCs. We have covered a few products from Arctic over the last 10 years, with most of those impressing us. Today it is bringing us the ARCTIC 33 eSports One CPU air cooler. With 4 direct mount heatpipes, a BioniX fan, and a new thermal coating, today we will see if this small cooler has what it takes on our overclocked Ryzen test system. The 33 is tiny in size when you compare it to many of today's coolers. Worried about it getting in the way of your first RAM slot? No issues there at all. This small cooler boasts this on its spec page:

Max. Cooling Capacity: 320 Watts - Recommended for TDP up to: 200 Watts

Given that our CPU package power on our test system peaks out at about 165 watts package power, we are hoping that this cooler at $30 with Prime Shipping may be just the thing your next budget build is looking for.

System Setup

Today's review takes place on our purpose built cooler testing system, featuring an AMD Ryzen R7 1700 overclocked to 3.9GHz, a GIGABYTE Aorus AX370-Gaming 5 motherboard, 16GB of Corsair DDR4 memory, and an ASUS GeForce GTX 670 DirectCU II TOP GPU. Full details of the test system and testing methodology can be found here.

Test Methods

CPU

Our AMD Ryzen 1700 CPU will be running at 3.9GHz across all cores and will be being stressed by Prime95 using Small FFTs in both our CPU only test, as well as our combined testing. Our CPU Package power measures ~170 watts under full load.

GPU

In combined testing our GTX 670 will be running Furmark in addition to Prime95. This puts an additional 250 watts of heat into the system that the cooler will have to contend with.

Case

Testing is being performed in our Obsidian Series 750D Airflow Edition Full Tower ATX Case. Chassis fans include two Corsair 120mm fans pulling intake duty in the front, and a Corsair 140mm fan exhausting in the rear.

Fans are set to a locked 60% speed during all testing, as we found that is the best balance between performance and noise.

Thermal Paste

Thermal compound being used is Promilatech PK-3 Nano Aluminum. This is a very viscous compound rated at 11.2 W/m and requires no burn in or setup time.

Temperatures

Ambient temperature will be kept at as consistent temperature as possible for the duration of the tests. Temperatures are being measured in 4 places during both tests using our Sperry DT-506 Quad Input Thermometer, case intake, cooler/radiator intake, cooler/radiator exhaust, and case exhaust.

Idle

Average idle temperatures will be recorded after a thirty minute period of system inactivity.

Load

Load temperatures are measured every 5 minutes from all four points with the Sperry DT-506 thermometer, as well as the CPU Temperature (Tdie) and Package Wattage as reported in HwiNFO 64. Both the CPU only as well as the combined tests are 1 hour long, at which point the average temperatures will be used as our data point.

Sound

Sound levels will be measured with a BAFX Products BAFX3370 Digital Sound Level Meter from a distance of four feet away from the side of the case. With everything turned off and the room completely "silent," the meter registered a sound level of 39dB(A).
