PCI Fan

Hey there guys & girls. I just installed a new pci fan and the temp dropped 2 degrees from 49 degrees celcius to 47 degrees celcius at idle (verified for more than 3 hours). But upon a shut down and restart, the temp now idles at 54-55 degrees and doesn't lower any more. No changes was made to the computer. The program i was using that told me the temp is speedfan. However, i had experienced many errors running it, before it finally got back under control, could i have messed up the sensors in my computer. Speedfan does not control the speed of the pci fan and unless the weather really turned hot, there's nothing that can account for the temperature difference. Does anyone have any explanations?

What type of fan is this? Make/model?

2 degress isnt anything to be excited over .... could have just been circumstances
 
Is the first temperature from a cold boot and the other from a i-just-turned-off-the-machine-10-minutes-ago?
 
The first with 47 degrees was a cold-boot. overnight, i let it cool down and cold-boot again, but temps still remain at 54. I think it's cause it's summer now and i don't have ac. Temps outside are around 79-80s.

1. Pick a temperature metric and stick with it.
2. Most likely just the ambient temp ... regardless, them PCI exhausts arent supposed to drop temps by more than 1-2C ever ... if even :D
 
WTF....... thats the whole point of PCI exhausts, they shove all the hot air out of the back and lower the ambient case temp by an average of 10 degrees. I have two and my case temp is down by around 15-17 degrees.

hehe at a piddly 14-20cfm in a cramped environment do you really think its going to drop the temps that much? Compare this to say an average of 30cfm in a prime zone for a stock 80mm.
 
yea, im with Praetor on this one:) , i used to have a pci exhaust on my system and it made the cpu temp even higher , there main purpose is to cool off graphics cards but why do u need one if u have a good gcf and good air flow through the case
 
I can see i'm not going to win this conversation. I have got one in my case and have noticed quite a big drop in temperature.... let's just put it down to coincidence then.

*EDIT*: Also, if you buy a cheap one then the motor inside will just reate more heat than it is getting rid off. Spend about £10-£15 and you WILL notice the difference.

Same here. I installed one thinking it would at the least cool my video card a bit better. All it did was add some noise and raise my temps a bit.
 
Nothing changed. I just assumed the PCI fan must have altered the air flow inside my case in a bad way. Maybe the air being pumped in from the bottom front of my case was never making it to the top exhaust fans because the PCI fan was sucking it all out. Anyway, I just took it as a $6 loss.
 
Ummm, the pci fan is at 35CFM max...

1. Fair enough and the biggest baddest thing i can connect to a 80mm hole is 265cfm. Whats the point? Most PCI exhaust coolers arent 35CFM and most 80mm vents arent pushing 265CFM
2. Link is dead for me
3. Regardless you can have 35cfm in that exhaust and yer not gonna be cooling much down simply due to the fact that the PCI slots are a poor position for the cooler


The big heater of a case is the CPU so any cooling should be positioned there ... like a rear 80mm exhaust for instance.

Well the only really useful application of them PCI exhaust coolers is to supplement videocards (now... that wasnt their original design intent though). But one does have to be careful not to create a conflict of air between the video card's fan an the exhaust cooler
