Correction Review: Silverstone Heligon Series – HEO1 CPU Cooler Revisited
WHAT WE LIKED:Zero RAM Interference, 2 modes of cooling performance, Capable of handling overclock settings
WHAT WE DISLIKED:Fan in P mode is loud, Large Cooler may pose problems on some motherboards.
To re-test this cooler we used the exact same set-up as previously. When testing the Silverstone Heligon Series – HEO1 CPU cooler, we are going to boot to windows and let the system idle for 10 mins. We will then measure the ambient room temperature at the time of testing. This will ensure that we give you the most accurate results across the board. However this time around to rule out any variances, we ran the test 5 times and took the avg (middle) of the batch to be on the fair side. The variance of temps across all cores is +/- 5 degrees. All bench tests are performed in Celsius.
To run heat testing we used Prime95 as our software of choice. We ran Prime95 for 25mins to give enough time for the CPU to process all the loads. We record our temps with Core Temp as we find it to be the most accurate. We also tested the chips at stock freqs and with OC freqs to give you an idea of how this cooler performed.
Our test set-up for Intel Socket 1155
Motherboard – ASRock Z77 Extreme 4
Chip – Intel i5 3570k
RAM – Crucial DDR3 8GB Ballistix 1866mhz
PSU – Corsair CX750
GPU – XFX HD6870
Case – Dimastech v2.5 Test Bench
SSD – Kingston 120GB HyperX 3K
Since this cooler has 2 modes, Q & P. We tested both the same way.
First we measured ambient temps for the first test, which were 24c at that time. We tested our i5 3570k at its stock core of 3.4Ghz with voltages at stock as well. This test was ran in Q mode and once Windows loaded, we allowed it to idle for 10 mins and we measured our idle temps to be 24c at the lowest point. During that time we did see temps move around and avg. between 26-31c between the 4 cores. Without problems, it idled at our ambient temps.
Once the results were noted we loaded Prime95 and fired up the stress test in blend mode for 25 mins. As you can see, the Core Temp peaked at 52c with temps hovering around 48-51c for our avg. These were great results over the stock cooler that is included with the i5 3570k.
Next we shut down the PC and switched the cooler to P (performance mode) mode. We allowed it to idle for 10 mins and we measured our idle temps to be 23c at the lowest point, while this shows it was the about same as in Q mode, be sure to keep in mind that ambients were still at 24c, so the lowest dip on the temps were at boot up. During that time we did see temps move around and avg. between 25-32c between the 4 cores which are the temps we should be paying attention too. This shows that the performance was slightly better on some of the cores, but overall was about the same at idle.
In P mode, we did the same thing and loaded Prime95. We fired up the stress test in blend mode for 25 mins. As you can see with the Core Temp screen shot we peaked at 51c with temps hovering around 46-50c for our avg. While this didn’t show the cooler performing a great deal better, it was ever so slightly cooler, which is still great.
Next we wanted to see how the Silverstone Heligon Series HEO1 would perform under our overclock settings. We bumped the core clocks to 4.4Ghz for our testing and set the voltage manually to 1.30 volts. Remember the OC voltage settings are different with every chip and vary per batch. The chip that we tested required the 1.30 volts to run Prime95 at stable settings.
We switched our fan back to Q (quiet mode). Then we reset the system and let it idle for 10 mins. As you can see here, idle temps weren’t much higher considering the overclock… Idling at the lowest point of 27c and averaged temps of 30-35c between the 4 cores. We had one core take a slight jump to 46c while the system was running programs in the background. This is not something unusual so it didn’t alarm us.
Next we put Prime95 to the test in blend mode, and after 25mins of load testing we achieved 69c as our max peak, and averaged around 63-69c for the most part. At these voltages these are excellent results. As you may already know, the Ivy-bridge processors run higher temps due to the new architecture and chip TIM design.
Next we did the same test after shutting down the PC. We then switched to P (performance mode) mode, and allowed it to idle for 10 mins. We then measured our idle temps to be 26c at the lowest point. In P mode this time around items temps dropped a bit showing us some better results. During that time we did see temps move around and avg. between 26-35c between the 4 cores.
In the same P mode, we did the same thing and loaded Prime95 and fired up the stress test in blend mode for 25 mins. As you can see with the Core Temp screen shot, we peaked at 69c with temps hovering around 56-62c for our avg. While in the overclock settings, we did see some slight improvements while in P mode.
Now, lets take a look at some comparison charts from our previous testing so we can point out the differences. The first thing we want to point out is that since both coolers were tested at different times, ambient temps at the time of testing can play a role in the results. At the time of the first review our ambients at that time was 15c. During the re-test our ambient was at 24c, which is a 9c degree difference. So in order to account for that, we took our final results from both test and took out the ambient temperatures out as a factor. What we did was take the ambient temps from each test and minus this out of the equation and found our Delta T temps. For final temperature we took the avg. of the four cores to give us our total.
Example of the equation: Ambient = X, Avg Max Load/Idle Temp = Y ( y-x=Delta T)
As you can see from the comparison at 3.4ghz, the cooler performed better by 5 degrees under idle and load testing.
At 4.4ghz we also saw about a 5-4c degree difference under load testing.
So let’s wrap things up.
