降成十幾廿度既HS 真係未見過
我ONLY睇過REPORT用ULTRA 120 E6600 RM TEMP :20
IDLE : 43---->35
FULL LOAD ( 30MINS ) : 59 --- > 47
可能我眼光咁淺陋

CHECK IN EPX
WITH FAN BUT DUN KNOW THE DIAMEMTER
WITHOUT OC AND DEFAULT VOLTAGE
YOUR SO-CALLED COMPARISON WITH WATER COOLING & ULTRA 120 IS ALSO WITHOUT EVIDENCE

其實各有各好既=]
水冷效能大唔大係講求佢既水流大唔大..設計水道方面完唔完善..水阻大唔大咁..同埋個冷排效能好唔好
而風係要求機相對流做得好唔好同散熱器設計既散熱面積大唔大..道熱好唔好..兩者效能我覺得 ...
消費能力高既話水冷係一個好選擇

THE EFFICIENCY OF WATER COOLING DOESNT COUNT ON THE WATER FLOW !!!
THERE ARE 2 TYPES
1 . 高壓力
2 . 大接觸面

specific heat capacity 係 based on material
根本水既chemical nature冇變 點降低heat capacity
可能我phy太廢![]()
就係加入左冷卻濟落去令到混合物既熱容量低左原帖由 葉// 於 2007-8-19 08:17 PM 發表
e=mc︿t
e=能量...m=質量...c=比熱容量..︿t=溫度
如果水既質量不變..能量不變..但熱容量低左..自然溫度就高左(姐係水內溫度)
自然水既導熱性高左...水冷既效能就因此又提高左![]()

只係mixture of coolant & water
但in fact , water既chemical nature doesnt change .
都係咁多水都係要咁多energy

唉...佢講極都唔明咖-____________-
算啦...係咁係度講化學..但佢又唔明白混合物既化學性質同物理性質...依兩樣野都分唔開就唔洗同佢地講啦/_\

CAN U SURE THAT THE C OF UR COOLANT USED IS SO MUCH LOWER THAN WATER
CHECK IT OUT IN WIKI
IT PROVES THAT COOLANT ALSO HAS A HIGH HEAT CAPACIT ...

it is not the case . Thermal conductivity mainly depends on the structure (how the particles are arranged)
of the material

i dun think chemistry & physics & biology doesnt have any principle related to one another
for instance , the great thermal conductivity of metal can be explained by the structure ( giant meta ...

其實我地講緊既野係唔係離開左水箱水既導熱性比水好依個話題呢-__-
其實好簡單囉..水箱水係混合左導熱性比水好既物質同水之ma-__-水箱水與普通既蒸餾水係兩回事
希望唔好再有1d水既熱容係改變唔到既所謂理 ...

你好~小弟愚問.........
水箱水的效用不是防止锈蝕和電瓶效應嗎?
未聽過導熱性會比水好=o="
同埋如果話水箱水既導熱性較好......咁唔通成set水冷既水都係用水箱水=o=?

even in view of only CE level, water as a coolant was mainly due to its high specific heat capacity, as well as high specific latent heat of vaporization.
but not to lower its heat capacity ...

經驗?經驗話我知,
ultra120 ex將q6600呢粒煲水cpu係full load時降到得番4x-5x度左右
你唔識爬文都唔該你逐頁睇下d會員名

I did not say that we can judge whether it is a coolant by looking into its structure
But i only point out the golden fact that the thermal conductivity hinges on the structure of the particle ...
