pci blowers

[evildoc614]

Iam just wondering if thes pci blowers are very loud? i just cut the honey comb from the back of my pc but i cant tell if the temps have drop. my wife has been using the oven all day so the temps in the apartment are 10F hotter then normal. i just wondering, and i cant find a US site that has the S3 or S4 noise blocker any one seen them around?

pci blowers imo are useless and do almost nothing to remove the hot air

[Darkmatter]

Id have to second that. They are very quiet but then again they dont do much, their quoted CFM figure is IMO false.
They taper the exhaust part along the slot down to just a small spot which gives the illusion when you place you hand near of a greater airflow.

When i had my Dual XP rig PCI blowers helped a lot! Its removed the hot air from the PCI cards nicely. Itll drop case temps by a couple of degrees but it wont impact CPU temps much.

depends where the blow is really - at the local lan i went to there was a guy with a zalman heatpipe on a radeon 9600 and as a PCI blower right next to it. i asked him if he noticed any differance - to which he replied if it wasn't there the card would over heat. as it was crashing out of 3D mark before he installed it.

does depend on who has made it but tbh i wouldn't get one.

I took my PCI blower out, didnt seem to make any difference..

I had one of them in an old 450 I've got lying around, not sure of how much of a difference it made, but it died last weekend. Making a terrible noise. It was only about a year old! Nice idea tho!

Took mine out. Did NOTHING for temperatures and made an annoying noise (and took up a PCI slot).

They all depend on how good the existing airflow is in your case. As long as you've bought a decent case with well designed airflow (or have altered it too such) they won't make hardly any difference. I chucked mine out quite some time ago case it made no difference.

They are definitely useful as a quick fix to solve someone elses gfx card over heating in an old case though. Just don't buy the ones with two 40mm fans - loud and useless

I had one right under my voodoo 3 3500 (back in the day ), because it used a passive heat sink which got very hot. It cooler it down a lot, and enabled me to overclock it higher
Probably not much use in todays modern systems, but in old ones when airflow was rubbish and components were hotter they had a place.

I agree - useless and can make temp worse if you have the standard air flow. Even if you were trying to suck ait out down there and i cant think why, an internal fan would be better blowing air across and out the slot.

Agent i had same problem with a voodoo banshee a few days ago for my dads pc, a 40mm fan had exactly the same spacing between the holes so i took the pins out, changed the thermal paste and stuck the fan onto the crappy heatsink and used a m3 bolt to hold them on, now it seems fine

[Rythmic]

Yeah banshees - I remember burning my finger on one of those - Why they felt a passive heatsink was adequate for those things I'll never know.
