| 430363 | 2006-02-16 05:21:00 | sorry meg_h_nz i got your posts mixed with The_End_Of_Reality's posts. it would pay to start a new thread on yours rather than hijack this one. sorry Meg |

| 430364 | 2006-02-16 05:55:00 | I have some temps :) This is with the probe touching the heatsink GFX card HS 50C Idle CPU HS 35C idle Room 23C |

| 430365 | 2006-02-16 07:28:00 | What about the temp. of the air going into the cpu fan, or is that the 35C quoted? If the air flow through the case is reasonable, then maybe around 5 or 6 degrees above room temperature could be expected. If it is much more than that, then it is an indication that more or a better directed flow is required. I dont have experience of gaming type video cards, so I dont know how much heat to expect from them, but quite a bit judging from the size of heatsinks on some of them. The air coming from the video card heatsink shouldn't really be allowed to mix with the air going into the cpu fan if at all possible. That's where some ducting could be useful. On my Athlon Thunderbird 1.33Mhz setup with AGP V3400 TNT video, I used some cardboard to try to keep the flows from mixing. Meg_h_nz: One of the tools I use for sheet metal work is one of those saws that hold a piece of broken hacksaw blade. It is quite useful for cutting holes out, especially straight edged holes. Just needs an initial hole big enough to get the blade through. I also use a 'pad saw' with a jig saw blade in it. About 32 tpi for the saw blades is ok for thin sheet metal. But again, if you cut out that perforated area I'd do it with the case stripped bare, just to be on the safe side. |

| 430366 | 2006-02-16 08:34:00 | Not too sure, the wind factor would cool it down will it not? Hard work, I have managed to drill holes (gone through 1 battery already :horrified ) and use sidecutters to cut a hole, all I need to do is get a file and smooth it off, BTW that is only the first out of 4 :waughh: I will order a file in the morning :D |

| 430367 | 2006-02-16 09:10:00 | Snap a few photos as you go, you will surely monitor the temps after your modification, would be interesting to see what was done and the result. | Rob99 (151) | ||
| 430368 | 2006-02-16 18:01:00 | Sure thing Rob, after cutting out 1 hole, I noticed a 4-5C, somethimes more drop :eek: from cutting one fan!! they must have been unable to get any air in :lol:, I kept the door of the room shut to keep all heat in aswell, the room is the same temp now as it was lastnight, and I am doing some video encoding, exactly the same one that prompted this query, currently the CPU is at 43C and system is 40C, now that is a huge drop from one fan :D | The_End_Of_Reality (334) | ||
| 430369 | 2006-02-19 18:12:00 | Ahhh, have finally finished the moding :D. system temps are down by 5C and CPU is down 10C. here (www.imagef1.net.nz) is the finished product, here (www.imagef1.net.nz) is with the pretty lights on :D and here (www.imagef1.net.nz) is with the pretty lights and cover on :D The noise of it is also down a lot, will test that later. Thanks to all who helped me and helped me decide not to put a great big hole and fan in the top :thumbs: :D |

| 430370 | 2006-02-19 18:58:00 | That is a big improvement. Now you need to examine whether there is an equivalent flow area into the case at the front, so that those 4 fans aren't struggling to suck air in. :thumbs: I'm going to gather the bits together to measure the flow reduction arising from using perforated grills for fans. It will probably be a week or two before its ready. In the mean time: Turn On The Heat (www.petefaint.co.uk), Jack Hylton and his Orchestra, with Sam Browne |

| 430371 | 2006-02-19 20:41:00 | nice :) have you done the rear fans as well?? |
tweak'e (69) | ||
| 430372 | 2006-02-20 03:15:00 | Thanks :D No, the rear fans are larger holes, although I guess it never hurts to cut them, but I will later, when I have got some grills :) Terry can you please go into a little more detail of the equivilant air flow :thumbs: |
