When I did mine I din't use the mobo sensor for temps. I placed a temp die directly on the core. Seeing as temp sensor or with in .1% give or take I would say my temps were pretty damn close. Why not do the test with a direct die jet impengement style top. However I agree with your Maxxxracer as we should take a nice steel mallet and bash the skulls in on those who think they know everything. I'm willing to admit I don't but from what I have seen and done in the past, diert die is better.
Klown, i was refering to the senors.. but it works for most things also.. lol... the mallet that is.
interesting way of measuring temps. usually thats not possible... I wonder how accurately it measures temps.
I mean we have those who swear that their mbm or mobo temp reading is right on the money. Sad thing is they can be off by as much as 10C. Now with the heatspeaders theres really no way to place a temp sensor close to the core. Also A why would they make a direct die pelt cooling if direct die wasn't better. After all a 172 or a 226watt pelt puts out more heat then any CPU out.
Yes Max he did have something to say about it in this on ProCooling.Quote:

thanks for the link ancient.. i think that settles some things
Not very. Anything other than a built-in sensor is highly suspicious WRT to CPU temps. Typically an external probe will be placed on the edge of the core, which is typically much cooler than the rest of the core and not representative of the core temp itself. Direct-die only compounds the problem by making it almost impossible to mount a sensor anywhere near the core without having the water cool it directly as well (which would skew results completely).Quote:

Saying that I do not think that minor increase in surface area counters the thermal resistance of the materials. Also please remember Cathar is human and what he says should not automatically be accepted as the word of god...
Butcher I already thought of that.. I didnt want to mention it as... well i was too lazy to type it i guess and didnt want to start more stuff with Klown... but since you mentioned it.. lol...
Sewer, cathar ascended a while back. didnt you hear?
nope they dont let me out of my cage much :D
lol :p:
I say it as I see it, Max. ;)Quote:

Just remember tho Cathar in the begining said direct die was on par with the top of the line watercooling. However towards the end he goes against that. As said before tho he is human and his words are not written in stone. After all blocks like the G4 are as close as you can get to direct die with out having to worry about leaks. Don't worry tho Maxxx I just love getting under your skin.
ahhh!! get him out!!! the klown is in my skin!! i can see him moving around!!
(my spanish teacher told us about this guy who thought bugs were under his skin and tore his skin off and killed himself in the process.. he was on crystal meth)
well DD used to be on par with cpu coolers at the time. now days we have about 3-5C advantage over the early blocks of the time.
and cathar was fairly consisten in the post. he mentioned that DD at its best was about as good as a WW clone. And the clone probably was not as good as the origional. and now we have higher performing blocks so it is safe to say that his post was consistent.
ok your kidding about the guy and the bugs right? Correct me if I'm wrong but doesn't his G4 and G5 cool directly over the core?
they cool directly over it yes.. just like the tdx, rbx, WW, cascade, nexxosxp, and EVERY other impingement block known to man..
whats your point?
and no im not kidding.
Point is it's doing the same as direct die, just that it's safer. After all if direct die could handle the heat from a pelt, why couldn't it handle the heat of a prescott. Also man thats a heck of a way to go.
u dont understand is the problem.. the way the G5 works is WAY WAY WAY differnt than direct die. Cathar would be utterly insulted if you said that to him and bill would tear you a new one.
im not going to get into the thermo/hydro dynamics of the G5, but i can garuntee you it does not do the same thing as direct die. if you made a DD block where you drilled mico holes in the die with little pins in them and had jets from the block that when into the cups then yes it would be essentialy the same thing. but you dont. with DD you have water spraying at a flat surface that isnt the greatest at heat transfer in the first place.
Pelts are lower heat density so work better with direct die than CPUs. There is more at work than just the total heat output.Quote:
