    Hey there,

    Looking for some more advice. So I recently added water cooling to my system, but like I said my room gets rather warm, so my cpu (which is being cooled after my GFX card) is still managing to reach 59C when playing bad company. So, I'm think about adding one of these to my build(between CPU and waterblock. The one im looking at possibly getting is the 100W TEC Thermoelectric Cooler Peltier 12V.

    My concern with this though, is it will heat the too much :(

    Has anyone used one, know anything about them?

    Thanks..

    Dude...I know enough to say with confidence that they are quite extreme...esp if all you are doing is gaming and 59 degrees dont know your setup but if it an i7 that is fine and if it isnt slap yourself as measures like this are barmy?
    Interesting tho...esp the price...

    I wish I had an i7 =( I'm only running a quad core, but 2.66 been overclocked (one of overclocker's older bundles, to 3.2. I only started having problems when i had to move my system into a smaller (and much warmer) room. So I decided to move to water cooling. I thought my system should then run between 30/40C at all times with the WC setup... sadly not =(

    Well not that I profess to be an expert, but 59 is still acceptable, and if it does the job...
    Also doesnt sound like the problem is so much at your system cooling level but at actual room level. Can you get a radiator to outside the room?

    A radiator out side the room? If you are asking if i have access to a window, then yup, but the room is rather tiny, there isn't allot of space to put much else in it :(

    What size radiator do you have? Could you get a larger one in your case?

    I have a 360 and no I wont be able to get anything larger in my case :( i have two 180mm fans blowing on it as well.

    Well depending on how much sun the window gets, people have been known to mount rads outside in extremes, this idea just seems a bit too 'easy'. Having said that your temps are fine...why change things?

    Cos when I thought of this, I didn't realise that 59C was fine :p However with summer starting, I'm sure it will get worse =(

    build a radbox and stick it on the window sill, with some low rpm fans it'll stay nice and cool ;)

    Get one of those small fridges and keep your beer cool in it too ;)

    What cpu are you using?


    Peltiers are no longer powerful enough to cool modern proccesors without burning up.

    The more common option when using TECs is to run two waterloops with a seperate heat exchanger in both one cooling the hot side and the cold side cooling the loop with your cPU

    This may be of interes, it explains in more details on points I'm unsure of.

    I like the beer fridge idea, Or mod a freezer? :p

    I'd go with 2 loops, then each loops carries its own heat.

    get youself a couple of higher powered cooling fans and a fan controller for your rad/case.. Then just wack it up when you are hammering BC2 then drop down when you want quiet... Cheaper than messing with pelts and outside rads as well.. ;)

    Don't do it. You will kill your CPU and quite possibly your PSU if using that TEC.

    As pointed out, 100W is nowhere near powerful enough to cool an i7, especially an overclocked one.

    If you're even contemplating using a TEC, you have to do some research. Sticking a 100W TEC on your CPU which is probably doling out 150W of heat will result in it cooking itself, as the 100W TEC also pushes out 100W of heat.

    So to actually cool your CPU, you will need something that can deal with the heat from the CPU, normally a 225W TEC or something like that (that was the score when I looked at them back in the day) AND then get rid of that heat and the heat generated by the TEC itself.

    THEN you have to think about how to power that setup. You won't get a 225W TEC powered off a standard PSU - you will need a specialist 24V PSU (Meanwell for this. Then you will have to consider condensation: if you cool your CPU to below ambient, condensation will form and if your socket/mobo/TEC/waterblock isn't sufficiently insulated, you will get drips on all those sensitive components.

    Once you've done that, you will undoubtedly fry your GPU, because the massive heat dump into the watercooling loop will probably do a good job of keeping your GPU nice and warm...

    Think VERY CAREFULLY before doing this. 99% of the time it just isn't worth it as the cost is pretty spectacular to do properly (i.e. safely). And then, with modern hardware, the effect will probably be a bit of a let-down.

    Ask for MikeTimbers or samcat for more detail.

    Maybe get 3 120mm fans mounted on the rad rather than 2 180mm fans blowing at it.

    You need airflow through the rad, fans blowing at it will most likely just blow over it not through the fins.

    Agreed 3 x 120mm fans attached to the rad will be far better, also as your cooling the GPU in the same loop as the cpu, the cpu temp will be alot warmer then just cooling that alone, so those temps you are reaching whilst gaming are normal.

    Heres my example, as today is quite a warm day, i only cool my cpu, and running 2x 120mm fans on a PA120.2 at 500rpm, and whilst folding my cpu temps is 45C. IF i was to add a GPU into my loop, id be looking at the same temps you are. Its normal don't worry to much about it.

    Also what type of 360 rad, a thin or thick one?

    But deffinatly scrap the 2 big fans just blowing onto the rad, that won't help at all, you need to attach 3 fans to the rad for best performance, and depending on how thick the rad is, they can even be low rpm ones.

    dont think im being all to clear about the fans hehe

    My case is designed to have 1 fans blowing air upward and then I have an exhaust fan at the tope of my case pulling air out. The Radiator is mounted on the three fans (mostly only covering two of them tho)
    This is the design of the SilverStone Raven RV02, and it looks quite sleek as well.

    just stick 3x120mm fans on top of the rad and you should see a nice drop in temperatures, also trading the rad for a thicker one would be a good idea aswell.
