Cooling Questions on some parts regarding watercooling

I am moving to watercooling very soon and buying my parts 1 by 1.

Is Swiftech MCP600 Inline pump any good?
Does a Danger Den maze 4 fit a x800xt pci-e vivo card?
How does a 80.2 rad perform compared to a 120.1 or 120.2?

thanks

 

the swiftech MCP600 would work fine but hasn't it been discontinued? I dont think you can buy it straight from swiftech anymore.

the maze4 should work fine with your x800 since it supports most ATI cards including the X800 series (AIW is an exception)

As for the radiators --
Black Ice Micro 80mm: Rated for 236.6 KCal per hour (938.89 BTU per hour)
Black Ice Pro 120mm: Rated for 378KCal per hour (1501 BTU per hour)
Black Ice Xtreme 120mm: Rated for 790KCal per hour (3134BTU per hour).

You should be able to tell something from this information.

 

thanks for your help. I know the Pump has been discoutinued but i can get one for £25.

Btw, Dont understand the rad bit. Plain english please

 

Hmmm, plain english... *thinks*

The 80mm radiator is rated for 938.89 BTU per hour.

BTU (British thermal units) per hour is the amount of heat required to raise one pound of water one degree fahrenheit per hour, a common measure of heat transfer rate.

The Black Ice Pro is rated for 1501 BTU per hour. I think this is a much better number, a difference of 562.11 BTU/hr.

Now the Black Ice Xtreme with the thicker core is rated for 3134 BTU/hr. That's more than double the amount of heat required to raise one pound of water one degree fahrenheit per hour, compared to the Black Ice Pro.

That definition for BTU/hr came straight from a dictionary.

And also the ratings aren't 100% accurate if you use low flow quiet fans and such. You need a fan with nice RPMs and good flow.

Hope this helps you.

 

lol, im a noob i do kinda understand. So which one is better than 80.2 or 120.1/120.2?

 

120.2 is better. the bigger the rad, the bigger the surface area and the more heat it can dissipate.

 

In plain English: add up all the Watts of heat of the components you want to cool.

So, say, a P4 is about 110Watts while an Athlon64 is about 89Watts, a X800 is about 70Watts (if you tell me exactly what you're cooling, I can give you more exact wattage). A P4 and X800 would then be 110+70=180 Watts to get rid of.

Then see how many Watts a radiator can get rid of. This should at least be equal to, but ideally be much more than the total Watts of your components.

You know the BTU rating of the radiators. What Doomsayer failed to mention is that if you multiply that number by 0.29 you get the Watts that the radiator can dissipate. So a Black Ice Micro with a 938.89 BTU rating can lose 938.89 x 0.29 = 272.27 Watts.

This assumes, by the way, a 100CFM airflow through the rad. However the rad has some air resistance and roughly halves the CFM of a fan, so to achieve this you would have to put a 200CFM fan on it (no, you can't just use two 100CFM fans). That is pretty noisy.

A relatively quiet 120mm fan generates 70CFM. This creates again about half that, 35CFM, through the rad. So you really want a rad that can shed at least three times the Watts you need to get rid off.

In plainer English: the Black Ice Micro is crap. Go for at least a Black Ice Xtreme.

All the above is a rough rule-of-thumb, by the way, and are not precise calculations (that would get more complex). So nobody reply to this post saying: "that is not precisely so..." because we are trying to keep things simple, OK?

 

Yea, I feel stupid now for not mentioning all that. It was late and I was in the clouds

 

Thanks for your help Nexxo and Doomsayer.

I will be cooling these components

3000 winchester at 2.7ghz 1.5 (stock boxed cooler atm)
x800xt pci-e vivo
dfi ultra-d northbridge.

Thing is i have the Praetorian case and it has dual 80mm fans at front so i can use a 80.2 rad easily but if i have to go with the option off 120.1 then i would have to make a cut which i am not good with nor do i have the powertools to do that.

Do you think a 80.2 rad can cope with all that?

 

Good call on the rest.......might be worth putting it into some kind of sticky as it is quite confusing.

 

Btw, Is £9 inc delivery good for a nearly new Danger den Maze 4 block?

 

Considering it's $45 new on the DD site , I'd say yes, definitely, and that's without even bothering to convert $ to £ in my head....

 

LAst question about maze 4. How does it perform on a x800xt pci-e vivo?

 

About your Praetorian, it's probably gonna be hard to put a 120mm rad in the front of your case unless you can modify that HDD cage, and you also said you dont have the power tools...
I'd try to find a case that will better fit your needs, or I suggest modding. I dont know if a Micro2 will be enough to cool your CPU, GPU, and chipset.

 

I was thinking of selling my praetorian and getting a lian li v1000 in black. More w/c freindly but i love this case.

 

Will do. Tomorrow.

 

BIX what? Why not go for a heater core? It's nice and cheap, plus outperforms Black Ice type rads... eBay's motor dept is a great place to look, plus there are some with fittings as small as 1/2" OD and as large as 3/4" OD. Don't like the way it looks? Paint it!
