Default Hot summer days, hot computer problems.

Need help cooling in the summer.

Ok I have a Lian Li V1010B case with stock cooling. I have a Intel i7 920 with stock cooling and two Asus 4870 1GB dark knight edition. Here is the situation, in the winter months the room temperature is around 20 degrees and the CPU idles around 55 degrees, mother board is around the same and the Video card is around 52-55. Under a load I'm looking at around 75-80 for the CPU, 55 for the motherboard and 80 for the video card.

Right now this time of year my house is hot, my computer room is the hotest and is usually around 28 degrees most days. This is causes my computer to run hotter, obviously. Right now my CPU ides around 67-70 degrees and my motherboard is about the same. However my two videos cards idle around 75-80 degrees. Under a load my CPU is around 85 degrees, motherboard is about 67-70, and my video cards go to around 100.

Obviously these temps are within the manufactures limits but I want to run cooler and don't want liquid cooling. Any suggestions?

Upgrade the CPU HSF. Running stock HSF is not helping. For the board, an Antec Spot-Cool next to the NB does wonders. As for the GPUs, increase the fan speed or remove the side panel, and slap a house fan close to the GPU intakes. I used to do that a long time ago... works great.

Is there some way to get air to flow in/out of the room with a big fan of some sort, may drop the temperature of the room a couple of degrees, perhaps air condition if its an option though by the sounds of it, it is not.

The heat in the room is coming from my computer no doubt about it. If I turn off my PC the room temp drop 6-8 degrees.

I just installed a 120mm fan that I had lying around to blow onto the video cards and the motherboard. Video cards are idling at 66 degrees now and motherboard is a 54 degrees. CPU is still in the 66-69 range. This is obviously a lot better but it is a lot louder too. The fan is a Delta 120mm and that does like 145CFM of air movement and is almost 55db in volume. I can live with it but will look into a new HSF solution and maybe a quieter 140mm fan instead of this 120mm monster.

Maybe I'll install two Scythe SY1425SL12H 140mm fans. One where the 120mm is now and one in my 5.25" drive bays below my DVD drives. What do you think?

I'd reccomend an aftermarket hsf also. That should cut your cpu temps down by at least 10 degrees. Plus the rest of your case should be cooler because it won't be dumping as much heat into your case.

Your graphics cards arent doing any favors for the rest of your hardware though.

Are you running the vid cooling at stock bios settings? If so, you might want to bump the fanspeed up a bit manually (don't forget to do something with it before you game) in order to dump a bit more heat out of the case.

Depends on how noise adverse you are, but generally anything below 70% fanspeed is usually not very noticable.

Idling at 50C to 70C just doesn't seem right. Have you tried reseating your CPU heatsink?

As for your GPU, ramp up the fan speed and see if you can make the air flow better in your case. Also clean out the dust in your case with either compressed air or a vacuum cleaner.

Could try pop'n the side panels off and put a house fan blowing in (I have yet to see it fail to lower the temps) ...see if that helps for now. Otherwise...go buy stuff.

So any suggestions on a new HSF for my Intel Core i7 920?

I was sold on the Thermalright TRUE 1366 when I was air cooling.
