我在Koolance團購訂了一個冷排
http://www.koolance.com/water-co ... php?product_id=2034

但係唔識揀風扇，有人話SFF21F好，但係好似已經搵唔到了 :(

想揀一個靜的，$80一個左右就可以了...唔知有D咩好介紹

    SFF21F，A-SHOP樓下好似有，不過都要$120，如果 要$120不如一步到位GT1850...一定冇買錯
    如果BUDGET有限，用CM 風扇吧
    想要靜就要付出多少少，用係冷排上面一定係gt1850最靜，穿透力的問題

路過一問, 我用black ice GTX480, 20fpi, 用38MM FAN有冇需要?
定係用gt1850都已經可以?
因為好似black ice 既fin比較密, 所以用左38mm..

    fpl愈高，係需要更高既風壓先發揮到效能，
    散熱能力係會比較好，但換黎既係高轉速做成既嘈音。

    1850已好OK，用唔用暴力扇就要睇C-HING會唔會用嘈音換取效能，GTX越上越有的



補充一下，個test 佢地係用Gentle Typhoon 1850 (AP-15) 同 Gentle Typhoon 4250 (AP30)做的

因為有時我都會3930K 5.1G, 7970 1300/1850跑下分, 所以當初上水好自然用左衣把....
http://www.linkecomputer.com/pro ... 23812H-3000/Scythe/

不過時間耐左....就算而家我行單LOOP, 一隻GTX480>CPU+MB+RAM, 我開2把FAN ~30-40%都覺得嘈...

但係睇衣個圖又好得意...就3算我用低RPM既FAN隻GTX都唔會輸到PA120.3....其實真唔真?
我仲以為低RPM(1000-1500RPM)會輸比其他排TIM

---

作者: hgcjeffrey    時間: 2012-3-14 14:34

600rpm以下黎講都係輸少少，我諗佢地比較既都係用一類既排掛

8 GT AP-15 1850's push pull would be better and a lot quieter too.  20-30 FPI rads can really benefit from push-pull.

---

作者: Amuro0079    時間: 2012-3-14 19:43


Like I said, ap-15 push-pull would give the best balance between performance and noise with Black Ice rads.  Or you can go with ap-30s in push configuration and undervolt them using fan controller, but the ap-30s are a lot nosier than ap-15s at same RPM.  So ap-15s in push-pull is still my preferred setup.

That is why I said look for fans with very good static pressure.  You don't just look at airflow alone because the rated airflow is tested with zero resistance (static pressure = 0).  One of the reasons why GT AP-15's are so great is because that the static pressure is extremely high.

作者: majai214    時間: 2012-3-16 11:28



5.1g當然燒唔到機啦, 只係叫免強跑到3d mark06.., 行CPU test時好似見到係over 50度了
vcore1.46, pll唔記得1.8定1.9, vtt大約係1.25左右..

作者: majai214    時間: 2012-3-16 13:24



其實完全冇試5.1去燒呀, 5.1其實已經差不多係風/水冷既極限了, 再去燒機有一定危險性
不過新stepping可能有可能做到5G都燒到機, 睇下好唔好彩吧

They don't list it in specs, but Martin has tested static pressure of 120mm fans.  Sadly the link is dead:

When you OC'ed to 4.5 Ghz and beyond, do you notice strange behavior when powering on the computer after unplugging/replugging your power cord, turn off/on PSU, surge protector, etc?  When I hit the power button, the system would start up but immediately shut down for about one second, then it would restart itself and start POST'ing, and everything is fine.  Normal cold and warm boots are fine, only happens after cutting power completely.  I asked a few people on other forums and they have noticed it too.

---

作者: majai214    時間: 2012-3-16 16:19



我唔係好有印象有咁既情況, 因為有時setting唔岩, boot唔起都會著一下又自動關, 所以我都唔係好肯定我塊板係唔係都係咁

---

作者: Amuro0079    時間: 2012-3-16 16:24


If you don't unplug you won't notice it.    Do you turn the power completely off at night?

---

作者: majai214    時間: 2012-3-16 16:29


no i never do that

我而家用住Antec Kuhler 920 去預備"反"水冷，呢排試緊133x34, 燒機max 73-74c, 如果用custom水冷， 差個0.5ghz真係難上?

---

作者: majai214    時間: 2012-3-16 16:58



其實我知到好多SB-E上5G都唔係問題
只係去到4.8樓上燒機溫度太熱, 好難可以長時間行到, 好似你4.5已經去到7X度, 4.8可能已經去到8X-90度, 漠講話5G了

而家我粒U 4.5G要1.29V, 上到4.8G估計要1.37-1.39先stable到, 應該都好熱下...

Why not 100 x 45?
What do you use to  燒機?  Prime95, OCCT?

perhaps u r correct, it just sth perfectism XD
just like water cooling, some ppl may buy all expensive parts for less than 5c different ^^"
and sth also real, under the same total clock, lower multiplier (higher bclk) need less voltage and less heat production,
even just very little

I will try a CPU strap of 1.25x if I ever get some high performance RAM.  My current RAM is only rated 1866Mhz and I don't feel like OC them past rated specs, so I stick to  bclk 100 for now.
