0स्थिरता के मुद्दे

मेरे पास कुछ स्थिरता के मुद्दे हैं HTPC हाल ही में. एक पुनर्स्थापना ने मदद नहीं की इसलिए मैंने निष्कर्ष निकाला कि यह हार्डवेयर था. सभी गैर-जरूरी चीजों को हटाने में मेरी मदद नहीं हुई, इसलिए मुझे लगा कि यह होना चाहिए सीपीयू, मेमोरी या मोबो संबंधित. कुछ भी ओवरक्लॉक या ट्वीक नहीं किया गया है और इसके सभी हाल के ब्रांड नाम किट. मैंने तनाव का परीक्षण किया सीपीयू और स्मृति विफल होने के कारण या तो बिना, but I con­tin­ued to get occa­sion­al lockups and inter­mit­tent slug­gish performance.

Now because this is a htpc, it is in a smallish case with low air­flow. It has 2 120mm fans but they’re con­trolled based on सीपीयू temp and are usu­ally off due to low सीपीयू usage com­bined with the huge Scythe Ninja heat­sink. I knew the सीपीयू was­n’t over­heat­ing but thought i’d check the gpu (A pass­ive Radeon 5450) and hdd, which is in a sus­pen­sion mount­ing which reduces the cool­ing it receives.

How­ever both hdd and gpu were barely luke­warm. In the pro­cess I happened to catch my hand on the fairly sub­stan­tial chip­set heat­sink (labelled “giga­byte” in the photo below). आहा! I had­n’t real­ised that even with the sub­stan­tial cool­er the chip­set required or expec­ted some act­ive cool­ing from the nearby सीपीयू sock­et. I don’t have a fan dir­ectly on the सीपीयू heat­sink (as you can see below) and the air­flow over the chip­set clearly was­n’t suf­fi­cient. Ori­gin­ally I had the fans arranged blow­ing air out of the case, but decided to try a small rearrange­ment — revers­ing them and frac­tion­ally increas­ing their min­im­um speed. Pos­it­ive case pres­sure is gen­er­ally good prac­tice any­way, and this way air is forced past the heat­sink to exit the case. This small change seems to have done the trick.
Mor­al of the story: some recent(ish) chip­sets (e.g. Intel series 4 chip­sets) require reas­on­able air­flow (or a heat­sink upgrade — e.g. the Thermal­right HR-05 which is now on my shop­ping list).  It may also be a good idea to upgrade the thermal goop sup­plied with a high qual­ity com­pound. I recom­mend I C 7 Dia­mond if you can’t.
One final note — in my case the com­pan­ion south­bridge, with a tiny “heat­sink”, (cen­ter bot­tom of image) was only medi­um-warm and clearly does­n’t require any changes.
