![]() When things are staying cool the CPU and graphics card can either sustain their current performance for longer, or boost their performance even higher. When a PC component gets too hot it either triggers a system shutdown or, in extreme cases, a component ends up damaged. A computer's CPU and graphics card produce heat when in use, and thus you need some per-component cooling to keep things under control. Temperature is everything when you want to squeeze every possible ounce of performance out of your PC. That said, there are times when monitoring your PC case temperature can predict performance issues, though it's one of the last things you should be monitoring. Modern RAM usually does come with heatsinks covering the PCB (printed circuit board), however, and most motherboards include a heatsink for M.2 NVMe SSDs.Īs for the air temperature inside the case itself, as long as your components are cool that shouldn't be an issue. Everything else generally doesn't get too hot in most cases as evidenced by the fact that they don't have elaborate cooling systems. there is a suitable water block!!! Looks like it would *just* fit too but costs almost half as much as the board.It's easier to talk about CPU and graphics card temps since they have defined and well-known ranges. I have an opportunity to put a single 120mm fan right above the 9201-8i (and the adjacent NVMe SSD) if that downdraught from the radiators is not going to be enough.ĮDIT : Colour me surprised. It is about 20cm underneath the 120.3 radiators which I do admit push their warm air down into the case. I will end up using this card in my large ATX cube case from CaseLabs and the 9201-8i will have two empty PCIe slots in either side and the nearby GPU is water cooled. You can easily get replacements for $5 plus shipping. It is 35mm x 40mm x 9.7mm with the two push pins on opposite corners of a 33x33 square. I had a look at the spec of the heat sink that is fitted to the 9201-8i and it is a fairly small one designed for single-PCIe slots with no space for a fan. Out of interest, just how much airflow do these cards need? Are we talking about forced airflow over the card and out the back or is just being in a large space with mild flow in the vicinity enough? It is a real shame there is no onboard sensor we can query. Once my thermal paste and a full height bracket have arrived, I will take some pictures of the before, heat sink removal, cleaned and after condition along with a new idle temperature. I want to give it every help I can to get rid of the heat. Given that the SAS chip is producing so much heat and that the board has been sitting in a box since the date on its label of 2011, I will certainly replace the thermal paste. I did notice that even at idle in open air the centre of the heat sink showed 56C. I could only reach the heat sink side of the board so will not be able to get a back surface temperature. When it had idled for ten minutes, I checked the board with the IR thermometer. It would be easy to believe it was an unused NOS item. Even the PCIe connector pads were pristine. It was in perfect condition - not a fingerprint or dust mark on it anywhere. It had a half-height bracket so I temporarily removed that and carefully plugged it in to check the board as best I could. My LSI SAS9201-8i from eBay has arrived, well before my SAS cables.
