No intake fans (noob)

post #1 of 8
Thread Starter 
Hi all, I'm new to this game. I have a E6700 running at stock, on a Gigabyte 965P-S3 - I've got CIA2 on at Cruise, which ups the FSB from 266 to 288 under load. Anyway, I recently upgraded my heatsink from the stock Intel thing, to a AC Freezer 7 Pro, as SETI was pushing my CPU to 60C after a few hours (and that wasn't even the on-die temp). Much better now, with my CPU temp never getting past 50C (although the on-die temps reach 55C under load with FSB at 288). However, my only other fans are one on my Geforce 7600GS (which doesn't really count!), the fan in my 600W PSU (which is new, as my last PSU died a couple of days ago), and a small case fan - 80mm I think, at the back acting as extraction. According to Speedfan, my ambient temp (wherever it gets that from!) is 41C. I can tell you, that my room is NOT that hot - my thermometer has it at around 24C. I guess this is because I have no air intake fans in my case? I have a cheap case, and it is poorly situated (effectively enclosed in a wooden "box") with only 1" between side and back of the case, and the "box". How important is air intake? Also, what about dust ingress?

I've seen a product that will allow the mounting of a 120mm fan into 3 x 5.25" drive bays - is it a worthwhile upgrade?

I think you could just cut a 120mm hole in the front near the HDD cage(s) (if there is room, sometimes cases run the switches and LED wires through that area) and mount a 120mm fan in there somehow. Also look to upgrading your exhaust fan to a 120mm, moves a lot more air for the same or less noise than 80mm fans.

First off, pull that case out of it's cramped area! A computer in a cramped cabinet, regardless of cooling/number of intake-outtakes, is going to be recycling warm air and will have relatively high ambients...

Next, see if you have 4 or more drive bays... a 120mm fan can be wedged into 3xdrive bays using cardboard or other material:


Any further fan placement will require modding with a dremel and a cutting wheel or a drill and hole saw... A few mod ideas would be to cut out the rear 80mm grilling to increase airflow, cut out a 120mm near the hard drive cage, and even cut a 120mm on the top for a blowhole

Hmm, I'm not super keen on taking power tools to my case!
Rather take them to the cabinet, to be honest *lol*

You don't need tools if you mount it in the bay area, like I did.

(sorry it's blurry)

I'm up for that, looks spot on! I'm not so keen on the custom mod though, as I don't have confidence in my ability to actually make something! The only pre-made products I can find are the Scythe Kama-Bay and the Lian Li PC-343 Fan Module - are there any other mounts I should look at?

Both of them block too much air for my taste, and doesn't block dust. If you look at the mesh, there is as much metal as holes. All you have to do is remove 3 drive covers, stick a fan in there, and keep it tight using either zip-ties or balls of cloth, foam, etc. It saves money, makes you feel better, and pushes a lot more air.
