[REVIEW] Illegear Selenite Laptop (i7-8750H, RTX 2070)

Recommended Posts

Posted · Original PosterOP

Hi everyone. This is my seventh review in LTT forum. I will be reviewing the Illegear Selenite laptop. Main specs of the laptop are as below:

Spoiler

i7-8750H

RTX 2070 8GB

16GB 2666MHz RAM single channel

Samsung PM981 256GB

Intel 9560

W10 Trial

Mechanical keyboard (brown switch)

144Hz IPS

Kryonaut repaste and display colour calibration included

 

Based on TongFang GK7CP7S chassis

A few notes before reading:

1. This is a quick review; thus, not everything will be covered in here

2. This review will mainly focus on thermals instead of performance

3. I will often compare this model with its smaller brother – Onyx (read the review here)

4. My English Language is not that great since it's not my native language. I apologize if you find the review too simple and boring.

 

Product page: https://store.illegear.com/slim-and-powerful-gaming-laptops/180-illegear-selenite.html

 

Part 1: Build quality, input devices

Build quality is excellent overall, only just slightly behind Onyx. The lid has aluminium brush on top of it. There is only little flex when force is applied at the center. There is some flex when the lid is twisted, but not as much compared to Onyx. The lid has a bit of wobbling. You can open the lid with 1 hand. The body is all hard-plastic+soft touch build. Despite that, there is no flex on the entire keyboard deck and it cannot be twisted with force.

 

The mechanical keyboard (GENESWITCH v2, cap 2, brown switch) has low actuation force (slightly lower than the one in Onyx) and deep key travel. The switches are surprisingly quiet when pressed. Should be usable in quiet conditions such as in library. There is one complaint: The keycaps have some wobbling which makes typing a little uncomfortable. Like the Raven, the layout is a bit special (especially right CTRL and SHIFT keys) and I can sometimes mistype the up key when trying to press right shift. You can set the effect, brightness and speed of the keyboard lighting via the Control Center software.

 

The large Clickpad has Precision driver. The plastic surface has satisfactory smoothness but can be a bit rough when you have wet/oily fingers. Like the Onyx, you can disable the clickpad by double tapping the left top corner of the clickpad. The L/R click feel is OK, nothing special. Take note that the clickpad is located directly below the space bar; therefore, it’s aligned more to the left side. One minor issue: The clickpad has some noise when tapped hard on it.

 

Part 2: Display, Audio, Battery

The display is a 144Hz IPS panel from BOE (display ID BOE07B6). As you can expect from a high refresh rate panel, everything feels smooth. It gets bright enough, colours are vibrant, has low response times and good contrast.

 

The 2 down firing speakers has good audio (with a bit of bass too); however, you need to tune the audio via Sound Blaster software (otherwise the sound quality is terrible). Tuned audio profile: Music profile, bass 0, treble 3, surround 80, crystalizer 50, bass 40, smart vol 0, dialog+ off. Volume is a bit soft/quiet. Overall, the sound quality is slightly worse than the one in Onyx (with tuned audio profile too).

 

I don’t have time to test the battery life, however don’t expect much from the 46.74Wh battery.

 

Part 3: Cooling performance

The cooling design consists of 3 heatpipes with 1 shared on CPU+GPU. The heatsink is stretched to both left and right.

 

Notes on all thermal testing:

Spoiler

PL1 – 70W, PL2 – 85W

BIOS N.1.02, EC 1.03.09

GPU driver tested is 418.91

Test is conducted in an A/C room (ambient 20-22C)

Game mode and equilibrium mode are used (more on that later)

Laptop is plugged in. The fans take a while to speed up when load is applied

Max fan noise is ~54dBA

For some reason, the GPU has locked voltage (factory locked). There is no way to customize the voltage curve via MSI Afterburner (empty inside, tried many settings but no luck).

 

CPU Undervolt profile: -100mv on core and cache

Blue highlighted part is CPU undervolted result

 

CPU temp - Cinebench R15 multi core

Max 95C ~3.4-3.6GHz ~80W

Max 95C 3.8-3.9GHz 82-85W 1200+cb

Almost full fans for both

 

CPU temp - Aida64 FPU 70W

Max 90C 3.0-3.1GHz

Max 90C 3.3-3.4GHz

Almost max fans for both

 

GPU temp - Unigine Valley (extreme HD profile)

Clock speed fluctuates, at least 100MHz higher than boost clock (1440MHz)

Max 75C max 125W

Slightly reduced fans (compared to almost max fans)

 

FPU (with undervolt) + Valley (extreme HD) with max fans

CPU: Max 94C 3.0-3.1GHz ~50W

GPU: Max 75C same clock speed behaviour ~120W

 

Apex Legends 1080p all max, 8GB budget, 90 FOV (with undervolt)

CPU: Mid 70s, clock speed fluctuates 3+GHz 20-25W (see video below for explanation of the clock speed fluctuation)

GPU: Max 75C, clock speed fluctuates mostly sit at 1500-1600MHz range 115+W

Slightly reduced fans

 

Unigine Valley benchmark (extreme HD, 1 run only)

FPS: 95.9

Score: 4011

 

The chassis stay quite cool when it’s under load. Core temp differential is ~10C

 

In Illegear Command Center, there are 2 modes to choose from: Game mode or office mode. Office mode gives you access to control fan speed but has a 35W CPU power limit

 

There are also 4 power profiles to choose from:

Spoiler

High performance (same with Windows)

Game

Equilibrium

Power saving

Here’s a good video on how all the power setting works. Very informative. Basically, just keep it to game mode and equilibrium

 

The included power adapter is a 230W unit from Chicony. Take note that temps might be a little higher when running dual channel memory. 

 

Part 4: Miscellaneous

The laptop is very portable for a 17-inch gaming laptop while not sacrificing thickness for cooling room – 2.25kg and 25mm thickness. The footprint is also relatively small, just like typical 15 inch device.

 

You need to press about 2 seconds to power on the laptop.

 

For the positioning of ports and other pictures, you can refer Notebookcheck review on this model

 

Other settings in Control Center software:

Spoiler

Power source for display – turn off internal display

Display colour profile: Standard, Gaming, Video, Reading, Customize

Light Effect: Keyboard backlight, LED light bar

Other settings: Windows key lock, Hibernation USB charging, Discrete GPU ‘on’, Turn off OSD, Gamer mode

Conclusion:

 

Pros:

Spoiler

Portable for a 17 inch gaming laptop

Good-excellent build quality+cooling

Good display

Plenty of ports

Cons:

Spoiler

Poor battery life

Keycaps have a bit of wobbling - just a minor issue tbh

Thanks for reading! Let me know if there are mistakes in the review.
