Need a new 70mm CPU fan. Questions.

[00maxse]

I have a Thermaltake Venus 7+ heatsink/fan on my AMD socket 754 CPU. The fan seems to be having problems. It won't stay running most of the time. So I was wondering if I can just buy any 70mm CPU fan with the 3 wire connector and be ok?

Here are the specs on my Thermaltake. http://www.thermaltakeusa.com/2005/coolers/venus/si/a1770.htm

I was looking at this fan on ebay. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=012&sspagename=STRK%3AM EWA%3AIT&viewitem=&item=220132425303&rd=1&rd=1

It says the max CFM is 33.2 while my Thermaltake fan says 21.29 CFM at 32°C/41.95 CFM at 42°C.
They ebay fan says it runs at 3800RPM while the Thermaltake says 3050 10% RPM at 32C ~ 6000 10% RPM at 42C.

Will this be ok to buy this fan?

Thanks guys.

get a fan with the highest cfm. cfm is how much air the fan can move. the higher the better

Yeah I talked to a guy from a comp repair place today. he said I have to get a fan with at least the same CFM as the one that came with my heatsink. Higher is better though, but I can't seem to find anything in the 70mm size. 38 cfm is the highest I've found so far. (fan only, no heatsink)

well here's one with up to 46 cfm: http://www.overclockers.co.uk/showproduct.php?prodid=FG-035-AK&groupid=701&a mp;a mp;catid=57&subcat=818

Also, did you consider using a fan adapter to switch to say an 80mm fan? If you were to do that you could then use this fan, which produces about 85 cfm: http://www.newegg.com/Product/Product.aspx?Item=N82E16811999612

Oh thanks, but I think I may have figured it out. I might not need a new fan after all. Looks like one of my BIOS settings was wrong. I changed it. We'll see what happens.
