This rig is built 2.5 years before and acts as my main PC to browse Internet, watch HD videos, and play some old games (such like Age of Empires III). It was very noisy initially, and this gave me the chance to know SPCR and learn a lot of things here on silence. After recent upgrades, I'm pretty satisfied with its performance (based on my needs) and cooling result, but very disappointed on its noise level (as discussed in item 4). However, I can't wait to share this build with you, get some advices and continuously improve it later.
Antec Solo, Noctua S12@800rpm as case fan
Seasonic X-400 fanless
Intel Q9450 2.66GHz (TDP 95W), HR01 PLUS with SFLEX-E@600rpm
Apacer DDRII800 2GB x 2
Sapphire HD3650, AC S1 fanless
WD GreenPower 1.5TB EARS
Creative X-Fi Music
During the test (2010/10/03, 3:00pm@Beijing), the ambient temperature is 23C
!!! Idle (after system up for 10 minutes):
AC Power: 66W
!!! Load (CPU Burn + GPU Burn for 20 minutes)
AC Power: 154W
CPU Burn: Prime95 (Torture Test --> Blend)
GPU Burn: Furmark (Stability Test +Xtreme Burning mode)
PowerBay AC Power monitor (just like PowerAngel)
Everest Ultimate: Read temperatures
1 For CPU temperature, only Tcase is measured.
2 The actual fan speed (reported by Everest) is: Noctua S12 (~890rpm), Scythe SFLEX-E (~620rpm). Noctua S12 is a weird fan, if I open the side panel, its speed falls down to ~840rpm. If I reduce CPU fan's speed, it further increases. I don't know why
3 Gigabyte's DES (Dynamic Energy Saving) is disabled, and BIOS configuration is almost the same as default, i.e. Intel EIST (SpeedStep) is enabled.
- Disk is suspended.
- Case fan is mounted with rubber compensator.
- PSU Cooling is very good, just a bit warm during system burn.
- Personally I prefer simplicity and very dislike mod (due to poor skills). The only modding in this rig is AC S1 on VGA card.
- Originally I was going to replace HR01 PLUS with HR02, in order to build a single-fan meanwhile powerful system. Unfortunately this idea was dropped due to a compatibility issue between HR02 and Solo:
AmonRaa built a similar single-fan system (he cuts off Solo) but suffers cooling problem now
This build is quiet but not silent at all, for a couple of reasons:
- Resonance noise, lack of sound damping material. However, on local market it's almost impossible to buy any qualified material. I don't dare to try those cheap but not reviewed product (such like Lianli's PT-SI04), since once it's pasted to the case, it's almost impossible to remove. This is a pending issue.
- X-400 buzz noise: Fanless means zero dB? Of course not. In almost half times, this PSU is very quiet and generate very faint buzz noise (can only be perceivable within 10-cm). However, its state is very unstable. I have experience many times that its buzz noise bump up, which can be heard clearly within 50-cm, it's even louder than the 800rpm fan. I will open an independent thread to discuss this problem with other owners. I wish it's my sample's problem and can be replaced by a better one.
- Fan upgrade: After two years use, my SFLEX-E already becomes very loud, and Noctua S12 is regarded as an odd fan having poor cooling performance (in Xbitlabs' review). Will replace them soon.
- Get a SSD. I'm waiting for Intel's next generation though it's delayed to next year. And I can't decide whether I should get a larger one (e.g. 160GB) and move existing disk outside, or buy a small one for system (major for budget concern) used together with existing disk
