Help! Fan Placement & Airflow in Temjin TJ08-E Case...

[Cut]

Hi again all...

Ok - so all my components have arrived except for the motherboard itself (I'm assuming this is a pretty universal occurrence of Murphy's Law applied to PC building... ), so while I wait I've been imagining how everything is going to fit together.

My biggest problem is understanding airflows and fan control. Here is a picture of the build as I see it:

TJ08-E.jpg

Noctua NH-L12.jpg

The Intake fan is the 180mm TJ08-E stock fan. The HS is a dual-fan, blow-down Noctua NH-L12 (I was worried that a tower HS wouldn't fit). The GPU is a dual-fan Sapphire HD7850 OC which I assume blows out the air through the back of the card. The extraction fan is a 120mm Scythe Slipstream PWM (SY1225SL12M-P). The PSU is a Seasonic 560w X-Series.

I am hoping I can fit both my SSD and a 3.5in HDD into the bottom external bay so as to improve airflow. Or alternatively (if vibration is a problem) suspend my single HDD inside the spare 5.25 bay at the top.

My questions are the following:

(I do realise that a lot of getting it right is trial-and-error + testing + tweaking, but I'm not going to have much time for that right away - and this could end up being the only working PC I have available to work with for a while - so I'm hoping that with your help I can get it all as good as possible first time round... )

1. Is this fan/airflow layout going to work ok? Hopefully while keeping all fans running at low rpm?

2. Will I be able to control the voltage and/or RPM of all these fans using the ASUS Maximus V Gene motherboard & Fan Xpert 2? Does this include the GPU and PSU fans?

3. Temperature-wise - can I get away with just using one 92mm or 120mm fan on the HS? (i5 3570k CPU - not OCed now - I may in the future. It will be under load often though for Photoshop and/or gaming). Removing the top fan would lower the profile and maybe improve airflow?

4. Has anyone tried using this HS with two 120mm fans to improve sound compatibility?

5. Should I place the PSU fan-down (counter-intuitive and strange given the existing top vent in the case but recommended by Silverstone) or fan-up?

6. Will a 7,200rpm SG-Barracuda 3.5in HDD get too hot if it is not in the HDD cage directly in front of the intake fan? (the fan doesn't extend down to the bottom external bay or up to the 5.25 bays)

7. Do any of you guys with more knowledge than me have a gut instinct as to which combination might work best? (one or two fans on HS, with or without extractor fan, PSU fan-up or fan-down...)

Sorry for all these novice questions...

Thanks a bunch for the help

I think the TJ08-E is a great case, specially for a compact build, if you wish to see some ideas check my signature i did the micromi build on it. The only downside imo is the frontal fan which at stock low settings is still a very noisy fan, but below 600rpm is tolerable, if FanXpert2 is all the good that its said, the mobo should be able to control it.

Now with your questions,

1. Is this fan/airflow layout going to work ok? Hopefully while keeping all fans running at low rpm?

It should, the PSU will be passive until needed, so i so no issues, in my build i used a X660 and until gaming its a passive psu, the 560 should be fine.

2. Will I be able to control the voltage and/or RPM of all these fans using the ASUS Maximus V Gene motherboard & Fan Xpert 2? Does this include the GPU and PSU fans?

I only own the Gene IV Z, and i cant control 3pin fans, but according to asus, the Gene V should be able to control 3pin and 4pin, but this is something that only an owner could confirm, so keep looking. According to asus it can control all fans... but i have my doubts if its going to manage all case fans as one, but this is something that again only an owner will be able to say. Now the GPU and PSU.... you will need to cable them out and plug them to the mobo, i wouldnt do it, you would void the warranty on the PSU by opening it, and not worth it, as it is the X560 is a very quiet PSU should be passive if no load is applied to the PC. With the GPU.... imo not worth it either, you will need to cable to you mobo, but there is no need, with MSI Afterbuner you can control most of the GPU fans, i would investigate a little more into getting a good GPU that its not that noisy and control it with MSI afterburner.

3. Temperature-wise - can I get away with just using one 92mm or 120mm fan on the HS? (i5 3570k CPU - not OCed now - I may in the future. It will be under load often though for Photoshop and/or gaming). Removing the top fan would lower the profile and maybe improve airflow?

4. Has anyone tried using this HS with two 120mm fans to improve sound compatibility?

Im not going to respond on this as i dont own that cooler, but personally i dont think its that great, its more a low profile cooler and the TJ08-E can fit very high coolers, you can check my build, i fitted a Thermalright HR02 (not the macho version), with this in mind i would go with Thermalright HR02 Macho, cheap and big, the fan on it is very good imo (i also used it on minimi build). If you dont have access to it where you live, my choice would be Scythe Mugen 3, it comes with Slipstream PWM 120mm fan that can be drop down to 250rpm, so its very quiet and has good performance, you can see my HTPCmi build for temps, and i would add another Scythe Slipstream PWM (SY1225SL12M-P) for the back case fan, i think this combo should work very well, specially because the GENE V has dual CPU fans, so you can connect the CPU fan and the back case fan to the CPU mobo connectors having an even flow.

5. Should I place the PSU fan-down (counter-intuitive and strange given the existing top vent in the case but recommended by Silverstone) or fan-up?

Its up to you, the X560 will be passive on idle, so since hot air raises, i would install it with the fan facing up, thats how mine is installed and no issues.

6. Will a 7,200rpm SG-Barracuda 3.5in HDD get too hot if it is not in the HDD cage directly in front of the intake fan? (the fan doesn't extend down to the bottom external bay or up to the 5.25 bays)

I have a 7200rpm samsung F3 500gb on the bottom cage with an ssd on the bottom, and its temps are fine, check my build i have some hwinfo with hdd temps on it. Now there is no grommets to lower the hdds noise, so my recommendations is to invest a little more on an SSD, like crucial m4 or samsung 830, and get a green 5200rpm drive like WD Green Caviar, Samsung F4 or Hitachi 5k3000 for storage.

Good luck,

Thanks for the advice, Abula

I can see that I may have to make some changes in the future (Tower HS, 5,200rpm HDD and maybe even a new Phobya 180mm fan). For now (since it already arrived) I guess I'll try to set up my low-profile HS with just the one 120mm blow-down fan and then experiment. Hopefully, with the 180mm intake and 120mm Scythe Slipstream exhaust pumping air in and out I should be able to keep the HS fan speed lowish - assuming Fan Xpert 2 can control them.

Any info from Fan Xpert 2 users would be great.


I did choose the Sapphire HD7850 GPU because it is supposed to be quieter than most while still giving good performance - I hope that Sapphire also have sensible fan controls...

I already have an SSD (the Samsung 830 actually ) - so my question was concerning possible overheating with BOTH of them in the bottom tray (leaving the cage completely empty).

Nice looking build there btw, Abula

I installed mine on the bottom, you even have the advantage that the 830 is a 7mm ssd so you will have more room than me between ssd and the hdd, but i havent had any issues, my hdd temps are fine and the ssd been working for more than 6 months with no issues.

Good luck with the build.

Is there any negatives to the upside-down placement of the motherboard for this case?
