Realan E-I5/E-I7 mini ITX case builds - Page 3

i just swapped out my a6-5400k for an a10-5700 in my e-i7. My CPU package temps did not improve. i have three fans running exhaust, and am using the Noctua NH-L9a (37mm tall); i also hooked up a scythe Kozuti (40mm tall). The Scythe perhaps reduced the temps by one degree, but i am still running 46-48 at idle. Stardog, you mentioned seeing 35C at idle, was this the CPU package temperature? Could i be running too many exhaust fans? I can't imagine that the Noctua or Kozuti would cool less than the stock cooler. I am using the MSI FM2-A75IA-E53 motherboard; did you install the new bios?

Thanks for the info. Thankfully the asrock was out of stock so I got the msi fm2-a75ia-e53. It's to go in an e-i7 case

I am also running HW Monitor. At idle running 46-48C, 14W. I turned off blue tooth; machine is connected to network which could create minor power draw. When i stream hd temps watts range from 30 to 55 and temps 53-56C. Case is on an open shelf with no obstructions, below an LED TV which puts out little or no heat. I was pretty careful with cable management so box is not too cluttered.

by the way, i am using the 120W power supply.

Thank you. I would be curious to hear what you find. Do you know where i can pick up one of the 180w power boards?

Hi again , I just got the E-i7 and installed the MSI FM2 motherboard in it. Everything works fine except that when I request a shutdown, windows and the hdd stop normally, but then all the fans start spinning at max speed. Even when I disconnect the 24 pin and 4 pin from the mobo, the molex fans I have connected keep spinning. I think the psu has a problem, has anyone encoutered this before ? (this is not a mobo issue, as even when its disconnected, as soon as I plug in the main lead into the mains, the fans start spinning. )

Thanks for your help. All fans keep going actually. even if the mobo is completely disconnected, and I just plug in the external power bloc to the psu, the molex fans start spinning even if the psu is not getting an on command (the usual command given by shorting the green and black cable on the 24 pin cable)

I would have bought from you if I was in the us, but I have a local supplier who I have just contacted. He will probably end up exchanging the psu (I hope I don't have to send the whole case in ! )

test


Thanks. I suspect that there is solder or something short circuiting the green cable and and ground paths on the underside of the psu. I'll take it out tomorrow and have a look, if that's the case it should be pretty obvious.

also, I'm really interested in how you drilled the hole for the ir receiver. As I said I want to use a st-irpb, and was wondering what
you had use to cover the hole.

Do you have like a ledge or groove to fix the acrylic on ?
Also I tried out my build with a different psu, and it worked fine. So the Realan psu board is going back in the morning. Jopefully the replacement will work fine
Also from my short test, it looks like the cpu (A6-5400K not overclocked) with stock cooler and dvd drive, and the hdd vertical, with two 80mm fans on the right side as exhaust and running very slowly give the following results:
37-40 deg idle
55 degrees under prime (although I only ran it for 5 min)

What psu are you using?

If you were asking me, I was using a realan 120w lr1005 model. That's the one that wouldn't shut down. I checked it with a seasonic x660

Chluz, Thank you. My system works fine with the 120w Realan, but my temps are a bit high.

Do you have a optical drive and a 2.5 inch right underneath it? If so you need to put the hdd vertical on the side to give some clearance between the odd and the course fan. That improved my temps by around 5 deg I recall

i purchased my box directly from Realan. I will check the part number.

Now you're making me feel bad about my purchase
Serioulsy though, these cases are great for the price. they might be be as well finished as streacom cases, but they're the same size, more space for fans, and much cheaper when you account for the psu. Also I checked out the ecosmartPC barebones, these look sweet !

EDIT :
On another note, I finally figured out that the psu was not the problem, the DC input lead they gave me was wrong. It was a 4 pin lead,which I was plugging into the 4 pin plug of my board. The 4 pin plus actually turns out to be an output, whereas the 2 pin plug I should have been using is the input. More powerfull models use the 4 pin plugs as inputs, hence the confusion.

In any case, I also received the ST-IRPB. stay away from it, its not real eHome drivers and will not work properly with anything. Does anyone know of a good internal ir receiver that works with eHome drivers and RC6 protocol ? or an rf receiver compatible with allinone remote also working with eHome drivers ?

Thanks. I had a look at them, but it didn't say whether it was ehome devices or not. Is it actually a real ehome device?

got the replacement cable now, everything is working fine. I did have the issue of the system cpu usage going up when playing videos from a samba share because of an incompatibility with the bridged mode in virtual box and the network drivers. just leaving this here in case anyone else has that issue :-) waiting for the ir receiver from that place you mentioned now, they said it's ehome

just tried reconfiguring my ssd (making it vertical); there was no change in temps. I did find that if i drop one fan i get a 1 degree improvement in temps -- certainly no increase. So perhaps three exhaust fans pulls out too much air. With my noctua nh-l9a i have decent headroom over the heatsink. I have a feeling the difference is attributable to the power supply. I do notice that in idle, occasionally the wattage randomly pops from about 13-14 to about 40w and there is a brief temperature surge to the mid to high 50s (celsius). All i can think is that the power supply allow some periodic surges. I would not think that my configuration is stressing the power supply so much; the one you are using must be more consistent and generate less heat.

even with the top off and the drive bay (with the ODD and SSD) tilted up to allow wide open breathing room, my temps don't fall below 43-44. So, i have to attribute the difference to the psu.
