I am still using the original bigwater pump, which is rated at 31.7 gph (120 lph). The pump is placed outside the computer case and wrapped in tshirts under the desk. No noise whatsoever, although it does rattle (after 2 years of usage) and would have made noise if it was hard mounted to the case. O...

There is also one great aspect of steel, the price. I got the whole radiator setup (the radiator itself, barbs) for 30$. Aluminium household radiators were also avaliable with 3 times the price. But 10C above ambient at all times is more than I need. So aluminium was not necessary.

I am also using water cooling for my gpu. I have a 7600gs sonic with ddr3 memory, as other members have already spotted, ddr3 does not get hot. The rams in my card are factory overvolted to 2volts (default is 1.8), factory speed is 1000mhz, I am using them at 1500 right now, with no overheating. I'v...

Passive system with household radiator

I had a bigwater, water cooling system for a long time. I've ducted the radiator, changed the fan, added gpu and chipset blocks etc. But my main aim was to go all passive with the cooling solution. I had the idea of using a house hold radiator and finally had the time and ambition to do it. System s...

I've just skipped the idea of water cooling the harddisk. Wrapping in tshirts is satisfactory for now (as the ambient room noise increased due to the radiator's pump heating up all the apartment).

I've been reading reviews about the SilverStone ELEMENT ST50EF model, without the plus. This model also offers +80 efficiency. In my country Seasonic S12 500W is sold for $140.37 + tax, while ST50EF is $110 + tax. Seems like a good alternative. A spcr review would be great, might even alter the reco...

Thanks for the results. Can you also add the watt results for default voltage and default frequency. Also, can you add the systems performance value for each result (for instance superpi 2m results or 3d mark cpu results) so that we can create a performance/watt for each case. To see if undervolting...

A simple plastic fan grill will do the trick, no big deal (plastic, since you wouldn't want electrons sticking on a metal grill and charging it up). Besides, I looked at the specs of the unit. It generates 20kvolts with 50micro amps, multiply to find 1 watts output. There is no way such an output ca...

well it's actually funny.
But I've found those two modders talking about their designs in a watercooling forum.
They both agree that the middle active cooling is an overkill. So I'll do the cooler without the middle part.

That temp threshold does not have to make any sense. Initially 6600gt cards don't have temp reading enabled in the bios. You did a bios hack to get the values right? Actually that temperature you are reading is not accurate either. As there is no temp reading in the card, the manufacturer didn't bot...

i dont think your harddisk is working at 70C. You'll feel the heat of something at that temperature without even touching. I guess there is something wrong with your temp sensor on the harddisk. Try using your hands and touch the metal over the harddisk. If it feels hot, it is higher than 40C. If yo...
