[硬件求助]请老哥们帮忙看看这卡压力测试通不过是什么原因

前两天花了1300买了张公版的1080，一直眼馋10系的公版，感觉很帅[s:ac:哭笑]当时愿意多出点钱比市场价高200是因为卖家箱说全且有购买记录，并且成色还比较好。

结果回来各方面都测试了一下

3.甜甜圈(附上相应负载和响应温度)

跑完甜甜圈后没有问题就确认收货了，结果没想到忘了测3DMARK，后面一测就发现了问题

Fire Strike 和Time Spy比平均分要低

Fire Strike 和Time Spy压力测试都通不过

请问老哥们跑不过压力测试可能是什么的原因，我自己是猜测可能是公版散热不太行，加上过了四五年硅脂可能干了造成的，应该不会是显卡本身有什么毛病吧，现在有点慌担心能不能用个一两年[s:ac:哭笑]

另外电源是450w的振华铜皇，算了算应该是能够带得动的吧[s:ac:晕]
