Excellent 又有得學o野
我想請教o下
1. 週時見你o地講水阻, 但係就算推3 個 blocks, 大大個 Radiator(120x3), 除非空間所限, 要加長水管, 否則水道長度o係電腦水冷系統內都係有限, 水又 ...

1.  For tackling 水阻 you need to know the "head" of the pump as this spec will tell you how high a pressure it can provide.  This is different from the flow volume of the pump.

2.  Each radiator has an optimal flow rate.  Not always faster is better.  Remember water will need time to cool down inside the radiator.

而家只係第一編,未有咁快講到呢d問題,比d耐性,等我完成埋第二編就會開始講下效能呢d問題.....
或者到時已經有人答左你.......

Oh yes, 我真係心急咗

Thank you for your answers. Do you mean the "HEAD", the "Delivery Head"? If so, yes I can find in the spec from the pump but, what I want to know is how big the head loss to affect the performance of the cooling system. What the difference will be while it replaced by a more powerful pump? How do we find a suitable pump? For example, I'm using a small pump (From TT, 120l/h as I remember) for my Zalman ZM-WB2 and Coolwave 120x3. I run good enough now(acceptable at least, I think). A North bridge waterblock, Zalman NWB1 will be joined sooner. Can the pump support this additional head loss? Should it be replaced by a powerful pump? If it does, how good the performance will be enhanced? Of course, the most I concern is the "MONEY" cause the WaterCool has already consumed almost all my money. I 'm POISONED.
By the way, I'm so agree with your answer in point 2.

I only agree that each radiator has an optimal flow rate. But, it is still better to let the water run it faster before the radiator reach its diminishing return, right?

Pls read this article. you will know how to measure and select the stable radiator for you.

我用左好多方法都做唔到IDLE 去Full load 多3-4c
可以教下小弟嗎?

anyone?
please!!

The problem whether you should replace a higher head pump can be derived by factoring the heat dumped from the pump into the performance of the radiator (C/W). You can check the heat dumped by the pump from many of the on-line shops. Pls refer to my previous post and add the pump heat into the radiator's efficiency formula.

Still not use fans on your radiator?

i use 4 fan on the radiator, but still the temp is quite high
iam changing to TDX+D5 and Maze4 GPU with 3/8ID tube
