View Full Version : Beware of "Bunnies"!

I believe thats what techno geeks call the little tufts of dust that get all over the insides of your system.I thought I was fairly 'hygenic' in this respect ,getting the duster out every month at least but out of curiosity I decided to take my X800XT PE (graphics card and its Arctic Cooler (model 4)apart and dust them out and change the Arctic Silver thermal compound.....Well the inside of it was filthy with dust so I knew my recent high graphics cards temps were as a result.
So I put it all back inside my system with a new 'heat exhaust blower' type fan that fits into a PCI slot.I was astonished to see according to ATI Tool the core temps in game drop by as much as 15 or more degrees while the graphics card ambient temp was down at least 6-10 degrees(Celsius).I would say that the vast majority of this temp drop is due to the dusting as enclosed cooling fins had become quite blocked.Well worth under an hours work!

I've never checked it out, but I was wondering, has anyone seen or used an airfilter of some kind on their rig to prevent the "bunnies"?

Some of the machinery I work on has small filters on intake openings and fan covers that protect PCBs and CPUs.

I might have to rig up something here. http://forums.ubi.com/images/smilies/blink.gif

Airdusters are ideal for bunny removal, btw. It also helps to keep your work area clean! http://forums.ubi.com/images/smilies/25.gif

Case design has improved over the past few years, espically in the area of air flow. Two years ago I modded my old mid-tower to o/c a Barton 2500 to 200x11. The improved airflow decreased temps enough, I could lower volts and maintain the same system stability.

Having hardwood floors and a cat, I needed a filtering solution for my side intake. Working in commercial construction, I use the same temporary medium used to control sheetrock dust. Its durable and easy to clean using a vaccuum. If you're interested, I can post a few pics.

My case came with a filter(removable and cleanable) on the front fan.

All good advice.

I couldn't work out why my fans were getting faster and faster until I discovered that the inlet to the case was completely blocked by dog hair.

Now I check every couple of weeks. A good idea is to have the air intake as far above floor (or dog) level as you can.

Here is the culprit in my case:

Yes that would be interesting steve...Do you reckon the filter material doent slow down the air much...I reckon though my problems are in BIOS settings as my temps are very low -even gpu doesnt hit 50 with cooler.
Those 2-2-2-5 RAM timings/dividers/FSB etc etc are a nightmare....I thought I had the gist of it but apparently not.I can get a 4% OC on my 3500 (Winchester) and thats it ....Any higher causes graphics related crashes as far as I can tell......Somebody said I may be unknowlingly OC_ing my graphics RAM(?)....

His name is Pluto and he came from Bath Cats and Dogs Home as a stray, so we don't really know what he is. We think he's probably a Springer-Collie cross. Certainly a clever dog.

Our other dog is a pure-bred Springer (from a gundog breeder) - but she's so cute we don't normally post her picture on the web.

But just this once http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

I have an old maxitower with quiet and inexpensive coolers. What I did was to put a 12 cm fan and cut it in the side giving airflow to cpu, graphics and system. To that fan I put a little gitter with a suitable tissuepaper on. All the air comes from that fan, elsewere the flow is out of the cabinet. No dustproblem, typical temp CPU 40 -44 C (oc Barton 2500 to 2.4 /400) Gpu 28-55; x850 XT PE and system temp 25 C.

No bunnies and old cheapo coolers.

I read in a tech article somewhere that positive pressure within the case tends to prevent dust from sticking to surfaces. i.e. always make sure you have more fans blowing in to the case than sucking out. It doesn't prevent dust bunnies completely, especially around fans but they seem to form a lot slower.

Thank you, jetbuff, for getting us back on topic.

We're not talking about dogs here, people http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif . It's bunnies.

Looks like Ivan's rig has a turbo charger or something http://forums.ubi.com/images/smilies/16x16_smiley-very-happy.gif. Wonder how long I can leave the side of my case off before evil things happen? It does run cooler though and does a nice job of keeping somewhat warmer in the winter http://forums.ubi.com/images/smilies/blink.gif
