PC case : Dead silent!

Okay came here to put a post after some time. I stopped writing the Dear Diary series because I got some work to do. We had our research work and research paper draft submissions and mid review presentation. I barely slept 4 hours a day for last couple of days. So what I realized is there is no point of writing my shit in this blog crying that I didn't work. Instead I should work better. Sigh!

Anyway all presentations and shit finished yesterday. So yesterday afternoon I started modding the PC. If you have read my previous posts you should have known that I'm bit of a noise freak. I'm so sensitive to sound that I can hear the slightest wind moving. So this fan sounds in my PC are quite unbearable. So my first idea was to make an open bench case. So only the inbuilt fans will be included and no extra case fans will be needed as it's properly ventilated. But the problem is what if accidentally someone spill any drinks or food? Or some small insect goes into circuits in the PC? So I gave up that idea. Instead I had two choices. Get a silent case like Corsair 750D which is unreasonably expensive in Sri Lanka for a case. Or DIY mods to silent my PC. Actually Corsair 750D price is not seller's issue. It's that importing such a case takes a great amount of tax and shipping. Otherwise I would love to get a Corsair 750D for myself. It's such a lovely case! <3

So even though I can't exactly replicate Corsair 750D's design features, I could do that to some extend. So I chose the DIY path. I purchased foam sheets of 1cm density for $2. And that's for four of them. Dirt cheap! :D So last night I cut them for pieces and pasted inside my case for noise dampening. Soft materials reflect sound waves and hard materials absorb them. So I did basically the same thing which studios does. I used rough foam sheets to absorb sound inside the case. And included a fan controller plus a switch to control 2 case fans.



And results are marvelous! Absolutely lovely to say :) At 5v ( Lowest in fan controller ) I can't hear anything now. It's dead silent. CPU fan runs around 1150RPM it's noise is dampened by the foam sheets too. Intel stock cooler is shit! It's noisy. I will replace it with a Cooler master 412 soon. Don't like the look of 212 so waiting for a 412 which currently no one has stocks available :(

And also made a small stool to keep the PC under the table. So it should reduce noise when it produce under the load also. And I'm very happy with the end result now. Sweet. I can code peacefully now :D

So this is my desk now. PC gone under the table and only laptop and monitor and stuff are remaining. Simple and elegant! :)






Dear Diary : Day 7 ( Individual GUI Component Rotation in Unity3D )

Finally a somewhat productive day! I did some work on my project and what can I say it was a success. So I thought like this, if I get to know something cool, will add along the Dear Diary post series without making any new posts. I'm lazy what can I say :)

Lot of people have searched in Unity forums how to change rotation of individual GUI elements in Unity3D. Most of answers are using custom shaders and changing Matrix to do that. Well there's an easier way. Change the GUIUtility factors. Then they will be global to every GUI elements and every element would start to rotate. Now the fix is easy. You don't have to use complex matrix calculations.

1) In whatever the function ( in my case OnGUI() ) used to drive the code, execute the rotating ones first and then re rotate the Global GUIUtility factor by multiplying (-1).
2) use different script files for each GUI element.



And I decided not to do the skeleton build. I'm going to put a hold for that for now. Just because I'm broke. My HDD and CPU cooler are failing so I need to buy them asap. So no money to waste on metal strips and paints it seems. May be another time. And need to buy a keyboard too. From the day my asshole relative liquid damaged my DAS Model S, I've been using a Logitech wireless rubber dome keyboard. Now that one of my good friends revived my feeling for a mechanical keyboard, I think it's time to get one again. I guess I'll go with the Cooler Master Quick fire rapid. Because it's made by Filco which is one of the best mechanical keyboard makers in the world!

Nothing much for the day. Me out :)

Dear Diary : Day 6

Today was exhausting! I finished watching an entire TV series in one day. The Tomorrow People, very nice story. I always had a thing for genetics based stories. Real nice. Shame it has no any sequel. Another day wasted!


Anyway I'm planing to buy metal stripes for my DIY open air bench PC case. I already ordered PCI express extender cables. Need ti buy two decent wood boards and nut/bolts for tighten them up. And rubber sheets too. This is going to be awesome and my mind just sings for that :D

I'm going to get some sleep. Eyes are like burning :D

Dear Diary : Day 5

Well I didn't do much today. But most importantly I did two things. There is some poster presentation for our research project, so that poster is finished. And I designed blue prints for my case! Yes. new computer case. Actually it's not a case, it's a skeleton. I always wanted to do a open bench pc just because it needs very low amount of fans and it runs cooler than any case with good air flow. Why spend $180 on a Corsair Obsidian 750D when you can get same performance with less fans and less noise? As for the estimation the skeleton build will cost around $50. It's not so cheap compared to available cases in the market. For an instance Corsair 230T and Cooler Master 600 something are just 60$. And man that Corsair 230T is just frikking awesome! Just pure sex to eyes at that price point.

Anyway I saw this in a youtube video by newegg. I'm planning to do the same thing with a different style. I will add 2 step boards for Optical drives and another rail for power and other switches. So it's going to be somewhat different. Going to paint it black. And rubber sheilds everywhere I can possibly put.



There are some flaws in this rig because this was focused on a mining computer and not for an everyday computer. So I'm going to fix that by using thin rubber layers at fittings and under the boards to stop vibrations. It will work imho.

I sometimes wonder if I'm the only with sound intolerance. Seriously people don't want dead silent computers? Because most computers I see are like frikkin jet machines! LOL

Dear Diary : Day 4

Today sucked! And it was expected to be. Finished half of mid exams and other half in two weeks. So the hell are going to study on the next day :D So the only thing did was playing Alan Wake and Dota 2 for like 12 hours from the morning. About 9pm my head was spinning. Alan Wake is so amazing and I wonder why I didn't get it to play before.



Alan wake is super awesome. For a 2012 game it has the best graphics I've seen. At the efficiency per graphics output this game delivers, I think ubisoft should be ashamed of their sucked ass Watch Dogs. Everything from vehicles to mountain scenarios looks so awesome. Mind you that this is a 2012 game. I'm so excited to finish this game. But I'm long way from that for now :D

And tomorrow I'm going to take measures for my rig build. I'm going to make a open air chassy. And let's see how it will go.

Have to complete my project. I won't be able to integrate CUDA in to that at this rate of developing. I'm so sad about that. At least should finish the project though. I'm so sad about that :( And there are no very large data sets in it. Part of my mind says CUDA will actually slow it down due to the memory transfer time due to Unity's slow ass responsive.

See you later folks :)
