Airflow Suggestions

Hey

Thanks in advance for the help..

Recently my processor and mobo are running pretty hot.. Not sure if its the heatsink, the psu running hot or just not much air flow.. I dont overclock, so never really worried bout it. I had one case fan running on the side panel, almost directly across from the processor... I normally leave my computer on all day and night..


Recently the temp is getting up to mid sixites and mid forties on the proc and mobo respectivily.. Not sure what is going wrong here... My heat sink fan is moving and so are the psu fans.. I went out and bout 3 case fans thinging that it might help all 80 mm.

Here is a link to the case i m running
http://www.newegg.com/app/ViewProductDesc.asp?description=11-124-070&depa=1

Two fans are on the back of the case blowing in, and on in the top blow hole blowing out, since I did not purchase a 120 mm, couldnt us the front asn an intake and the back as a exhaust. The problem presisited..

What am I dont wrong? Any suggesttions on cooling my cpu down?

:Vomit;

Get those two rear fans on exhaust, make the side fan intake, and add the front intake. Take the top blowhole fan out if need be, and just tape over the hole.

It's also summer, you know. It tends to get hotter this time of year. 🙂

Ge...I think it has more to do with the Summer heat sinking in and what I do is run 1 flow from my Airconditioner/House Duct to my Case when the humidy sets in :light:
 
For some reason my old WD 13GB drive used to get really hot after long periods of time while running so I used 1 in 1 out setup for my front 2 case fans, had my window fan blowing in towards the processor and the rear fan pulling the hot air of the processor and out of the case. Worked well to keep my CPU/HDD cool but now I've replaced that drive and am thinking I should turn the fan thats blowing outward on the front back to blowing in. Not sure this makes a difference but I'm going to try it. I'd strongly suggest checking your HSF and PSU for dust buildup as well. If need be use a can of compressed air to blow out any buildup. This can cause quite a heat buildup unexpectedly and is much worse in a household with pet hair around.
 
Thanks for your suggestions.. I will make some changes tonight and hopefull correct the problems..

Thanks!!!
 
side is intake, rear is exhaust for hot air from cpu etc. top is exhaust. you need air moving front to back. you need to cool other things like harddrives. you probably need to cut out those fan grills that do nothing but block air. lousy cheap cases tend to have pinholes. case fans really have low static pressure ratings. any obstructions are bad.. let alone pinholes
 
drill holes close together in a circulat pattern then use a de-burring tool to smooth out the edges - (wear gloves - added so i don;t get sued 🙂 )
 
I used a pair of decent Wire Diagonal cutters. Took bout 20 minutes for my SuperlanBoy front grille (much thicker!). This kept the area free from metal dust - which is very bad for electronics. You might want to deburr if afterwards though, or just remember never to stick your arm near there.
 
heh it is simple. u go out and buy those huge 20 inch fan.... remove the side panel.. and have the fan blow out............. instance cool down............... if u want it cooler go water cooling or or use a mini fridge. gl

dremel

there are many "blow hole" or "fan hole" mod guides on the net. google brings up bevies, and thats how i got comfortable with the idea of doing it myself. see how others do it, various techniques, choose one🙂

fans 101 on the side is still good

Ha! I just had to laugh, seeing that case with the huge fan in the front. That's a really good idea though. I used to own one of those cases, it seemed well-built and solid when I bought it, but I found out the hard way that the airflow in that thing is HORRID. Those little "dimples" in the front case, IIRC, aren't even intake holes, the only intake is through a small 2" gap _under_ the front plastic bezel. So if you actually set the case down on something (and it didn't include feet, IIRC), then all of your case air intake is blocked by default. Like I said, I found out the hard way, I lost an Intel OEM i430HX mobo in that case due to overheating, it wasn't pretty.

Nowadays, I choose a case more on cooling and drive bays than looks. I currently have a Codegen 6049 (I think), the one with 5-6 hidden 3.5in drive bays in front, and a blowhole on the top, along with front and rear fan mounts as well as front-panel USB and audio. Kind of cheaply-built, I wouldn't really recommend it as a quality case, but could be a fun opportunity for modders, and good for LAN-party and OC'ing due to the built-in blowhole. I find that it reduces my case ambient temps by 2-3C.

One thing about it that I don't like, and had to spend several days doing metalwork on, is the internal 3.5in drive bays. If you choose to put a front intake fan in (where they provide a space), then the HDs get pushed back far enough, that the rear HD mounting-hole doesn't line up. I had to drill out another mounting hole at the back edge of each drive space.

I also drilled a lot of intake holes through the front plastic bezel at the bottom, for better intake airflow. You have to remove the plastic snap-in colored piece before doing that though.

It does have "screwless" entry, with a single thumbscrew at the top back of the case, and "screwless" card slots, with these locking plastic sliders. After thinking about it some more, these "easy-access" features may be good for compulsive upgraders and modders and testers, but may not be so good for a LAN-party box, from the perspective of security, someone could open up your machine and steal parts fairly easily. There is a small security tab in the back, that you could put a lock into, but it looks like it would be easy to snap off with a pair of pliers or cutters or something. The whole case is kind of cheaply-made too, there is some small vibration noise from the fans coupled into the side-panels if you're not careful.
 
Those two rear fan grills are horrible! It's almost like mounting a fan up against the side of the case with no holes at all.
Fans blowing out or in, whatever... Cut those things out! A jigsaw and Dewalt metal cutting blade will do the trick.

BTW, Remove the MB and other components before doing any cutting.
 
Could be dusty.
I cleaned my computer out yesterday, and I now own a new rug.

It's good to have a single direction of airflow on your computer. For mine:
3 intake (2 front 1 side) on the bottom half.
3 Exhaust (2 back 1 top) on the upper half.

This creates a terrorist arrow of airflow inside my computer, and the top exhaust lets trapped heat escape.

For more information about terrorist arrows, google plsthx.
 
I finally had to drop in some Tt fans to replace the lame RaidMax fans that came with my box. Of course they're now way too loud but my box is nice and cold.
