Deepcool GamerStorm Lucifer CPU Cooler
Our test setup is as follows:
- Biostar TZ77XE4 Motherboard
- Intel i7-3770k
- 8GB Mushkin Blackline DDR-3
- Thermaltake TR2-RX 1000W PSU
- Kingston 90GB SSD (OS)
- WD Blue 160GB HDD (storage)
- ASUS 24X DVD Burner
- Primochill Wet Bench
- Windows 7 64-bit fully updated
All tests are run using Arctic Silver Alumina thermal compound for comparison purposes. The CPU and heatsink is cleaned with Arctic Clean and Arctic Silver Alumina is reapplied. Tests are run at stock (3.5GHz [with 3.7GHz Turbo Boost]) and a moderate OC at 4.5GHz (no Turbo Boost). The system is left to idle for 30 minutes and a baseline temperature is recorded using CoreTemp. A Prime 95 blend test is then run for 30 minutes and the temps are recorded again. The recorded temperature is the average of the 4 cores. Since ambient temperatures can affect CPU temperature readings ambient temps are recorded during idle and full load testing. The ambient temperature is then subtracted from the recorded CPU temperatures resulting in a Delta T measurement, (or how many degrees above ambient the CPU cooler keeps the CPU). This levels the field for different ambient temperature tests.
Now I ran the cooler on the bench with the fan, then removed the fan and tested its passive performance. Under stock clocks it managed to actually do pretty well passively; however, under a 4.5GHz OC it failed miserably, hitting Tj MAX in less than five minutes. Notably it’s designed to run passively on lower-end CPUs such as the i3 series that have a lower TDP than our 77W i7-3770k. However I got to thinking and realized that on the bench there was no airflow at all over the cooler. So I decided to install it into a case (a Cooler Master Cosmos SE – look for the review on that soon), so it would have the typical airflow from the case fans which would more closely simulate real-world usage. Check out the results below.
On the bench the Lucifer in passive mode was able to keep the 3770k just a few degrees under it’s Tj Max and kept it from throttling down. In the Cosmos SE however (with 2x120mm intakes and a 120mm and 140mm exhaust) the temps dropped considerably just from having the case fans moving air. On the bench with its fan installed proved to be the best configuration and resulted in some very nice temps coming in less than 2ºC shy of the best on our list. The Lucifer’s fan is almost dead silent at idle and just barely audible under load at stock clocks. Let’s turn up the heat and see how she goes.
With a moderate OC to 4.5GHz the Lucifer with its fan fell back just ever so slightly while in passive mode both in and out of the Cosmos SE it failed. On the bench within five minutes it hit max and started to throttle while in the Cosmos SE it took about 15 minutes to start throttling.
Let’s wrap this review up with some final thoughts.
