Wireless not staying connected, fan issue?

[mark9117]

I was away and busy, but I'm back now. I cleaned out the box and turned the big fan over. I also took pictures.

Here are some quick before/after snapshots.
Note: I tried posting the pics here with img tags, but the forum insisted that pics are limited to 480 pixels high. These pictures are limited to 480 pixels in any direction. Mods might want to look at that.

Dustier than I thought. We'll see if it makes a noticeable difference.

I'll be back with further developments as they unfold.

Thanks again.

Would you be so kind to reedit the first picture or another, which shows all of the fans (BTW, what's that thing laying on the edge of your case which also holds a fan? part of the case?) and mark them somehow, with arrows or something the like so one can see in which direction they blow? Is there also a fan at the front of the case?
Airflow is really important in such a small and packed case.

Okay, first pic is an annotated version of pic 3 posted above:

Note that all case fans are mounted to exhaust at this point (though in this pic, the 80 mm fan is not yet remounted to exhaust). (EDIT: I was wrong, this fan is mounted to exhaust in this picture. Mea culpa.)
Take special note of the 2 60 mm fans. One of them will be covered by the piece holding the 80mm fan when the case is assembled.




In this picture, the case has been reassembled and the 80 mm fan is positioned directly over the cooler stack.
You can just see the orange frame of the 60 mm fan on the right through the fan hole in the piece holding the 80 mm fan.



There is a 60 mm fan on the front, left corner of the case. It's positioned roughly behind that usb cable you see in the bottom left corner of picture #2. I couldn't get a picture of it and it isn't working. That's the one I have mentioned replacing, but it's a bear to get to and I don't have a spare on me at the moment.

That's about it.

Seems the cpu fan and the upper 80mm fan are fighting for the airflow
Maybe would be a good idea to turn it around so that it blows fresh air onto the cpu cooler&fan.

And you should really replace that front fan, currently the only one that would be relevant to put cold air into the case.
You should have no problems replacing it by any 60mm fan if it's a standard case fan.

I beg your pardon?

(from viewtopic.php?f=25&t=1700#p12683)
But back to the original issue, that fan, was it preinstalled? In general, the airflow basically goes
cold air sucked in the lower front, and hot air blown out through the upper backside. Normally you wouldn't want
to install a fan which just blows air into the case, because you also need to transport the hot air out again,
otherwise you're accumulating the heat in the case.

I appreciate your help, but I would ask that you make up your mind -- is your recommendation for the 80 mm fan in the top of the case to induct fresh air or exhaust hot air?

As is, I have just flipped that fan and I'm inclined to take a wait-and-see position in the matter to see if exhaustion will help control temperature in the case. So far, indications are promising. I'm watching a video under vlc right now and I'm seeing cpu temps in the low 50's and a gpu at about 70*:

Code: Select all

temp2:       +70.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = thermistor
temp3:       +51.0°C  (high = +80.0°C, hyst = +75.0°C)  sensor = thermistor

For some reason temp1 (core 0) isn't showing in sensors, but it does appear in gkrellm and it's roughly the same as temp3 (core 1).

Whether this is the result of the cleaning or turning around the fan, I can't say, but I'm going with what I've got for a while.

* These temps. are about 10 degrees lower than previously observed.

Well, you said all the case fans exhaust air, so the 80mm fan is blowing upwards, and if i've understood correctly the
cpu fan blows downwards. So for this particular setup (and as there's not much of an airflow currently at all)
my recommendation would be to set both of those fans so that they induct fresh air, as both the 60mm fans and the PSU fan
will take care of exhausting that.

Which was my thinking when I initially installed this fan. At this point, I think replacing the 60 mm induction fan is more important than turning this fan over again. I'm also seeing temps that indicate that I may be better off leaving this 80 mm fan in and exhaust position. I can replace the 60 mm for about $7 but getting to it is a bear -- I have to remove the hard drive cage and front panel. I will likely do that when I have some time this spring.

For the record, I'm streaming some flash video now and it's pushing the gpu (?) into the high 70's. Still not as bad as it was.

Thanks again.

It may be nice of a Global Moderator to adjust the topic of this thread to something with "fan" inside - the current title although correct in the beginning is somehow misleading.
(I also had the problem of continuously disconnecting with my Broadcom 4312 but it was in no way related to heat problems or fans)

[mark9117]

Agreed. The disconnect issue *seems* to be resolved.

As far as this thread is concerned, it has been fun and informative (those pictures are surely masterpieces), but I think it may have run its course. We could just let it go and I'll open another thread if something else turns up.
